About the Trimble DiNi Digital Level
Although the principle of leveling has not changed, surveying today is no longer confined to the measurement of height differences. A demand now exists for complex measuring systems, which not only meet the increasing requirements for automatization, digital data processing and last but not least efficiency in everyday surveying, but which also set new standards in technology and operating convenience.
The DiNi fits excellently in the complete line of the measuring equipment from Trimble: Data interchange between all the instruments is ensured by a common data format and by the use of the USB Memory Stick.

Care and Maintenance
C WARNING – Do not remove the instrument cover from the instrument. Trimble DiNi is designed
to withstand normal electromagnetic disturbance from the environment but it contains circuits that are sensitive to static electricity. If an unauthorized person opens the instrument cover, the function of the instrument is not guaranteed and the warranty invalidated.
The Trimble DiNi is designed and tested to withstand field conditions, but like all precision instruments, it requires care and maintenance. Take the following steps to get the best results from the instrument: Do not subject the equipment to rough jolts or careless treatment.
Keep the lenses clean. Use only lens paper or other material that is designed for cleaning optical equipment.
When not in use, keep the instrument in the instrument case.
Carry the instrument by the handle.
When you need extremely precise measurements, make sure that the instrument has adapted to the surrounding temperature. Significant variations in instrument temperature can affect precision.
C CAUTION – Never use strong detergents such as benzine or thinners on the instrument or the instrument case.
Be very careful when cleaning the instrument, especially when removing sand or dust from lenses and reflectors. Never use coarse or dirty cloth or hard paper. Trimble recommends that you use anti-static lens wad, a cotton wad, or a lens brush. Getting rid of Moisture
If the instrument has been used in damp weather, take the instrument indoors and remove the instrument from the instrument case. Leave the instrument to dry naturally. If condensation forms on the lenses, allow the moisture to evaporate naturally.

Instrument Description 3
Charging the Li-Ion Battery
The Dual Li-Ion Battery Charger (P/N 41114-00) is designed to work specifically with the Trimble Universal Power Supply with an 18 V 3A rated output (P/N 48800-00). Use of a power supply other than that specified by Trimble can result in damage to the outer housing of the charger, or can reduce the battery life cycles due to insufficient voltage.
The Dual Li-Ion Battery Charger LEDs show how the charging is operating.
When power is supplied to the charger, the green power LED is lit. If the charger is not receiving power, or the power supply is not supplying enough voltage, the power LED is not lit.
Temp (Red)
When the charger is turned on, the charger monitors the temperature of the unit. If the unit becomes too hot, the Temp LED is lit.
The Temp LED is lit if the ambient temperature around the charger is extremely high causing the charger to stop charging. If this occurs, unplug the charger and do not attempt to continue charging until the ambient temperature is within the specified range (0 °C–40 °C).
When a battery is inserted in the charger, the Contact LED is lit to indicate that the charger recognizes the battery and that it will be charged.
The battery must be fit properly in the charging slot or the Contact LED will not light.
If the Contact LED fails to light after you insert a battery into the charging slot, it may be that the battery voltage has dropped below the 5.6 V "sleep threshold". If this occurs, apply a 12 V power supply to the battery for approximately 5 seconds and then place the battery in the charging slot. The charger should then recognize the battery and begin charging.
When you insert a battery and the charger recognizes it (the Contact LED is lit), the battery will be charged. The Charge LED has three modes to indicate the status of the battery, as follows.

3 Instrument Description
Correction of the current line of sight inclination by a mechanical compensator Automatic alignment of the compensator ensures that an inclined line of sight is automatically leveled within the working range both for visual observation and internal electronic measurement. The compensator cannot be deactivated.
The working range of the compensator is ± 15´ with a setting accuracy of ± 0.2" or ± 0.5" depending on instrument type. If the inclination range is exceeded a symbol of a non centered bubble will be shown in the top line of the display.
A warning information is generated and has to be confirmed after releveling the instrument 30 Trimble DiNi User Guide
Instrument Description 3
The compensator has a major influence on the instrument's line of sight. For run centre adjustment, determine the residual line of sight inclination to permit distance-dependent correction of the measured values. For this, the Adjustment menu option on DiNi provides four methods. For precise height measurements, this check should be performed at regular intervals Angle Measuring System

The measured data and additional information is stored in the internal memory.
Data Safety
Data storage in the internal memory (non-volatile data memory without buffer battery) offers data safety for unlimited time.
The capacity of the internal data memory depends on the measuring mode, a line leveling with method BFFB will consume more lines then a single measurement.
It amounts to approx. 30 000 data lines. 32 Trimble DiNi User Guide
In this chapter:
Trimble DiNi User Guide 33
An instrument setup with good measuring stability will increase the precision in the measurement result and allow you to utilize the measurement precision of the Trimble DiNi to its full extent.
When a level is setup it is important to consider the following: Set tripod legs wide apart to increase the stability of the setup. A setup where one leg is placed on e.g asphalt and the other two on soil will still be a stable setup provided that the tripod legs are set wide enough. If it is not possible to set the tripod legs wide apart due to obstacles, then the tripod can be lowered to increase stability.
Make sure that all the screws on the tripod and/or tribrach are tightened to avoid any play.
Any survey quality tripod can be used. However, Trimble strongly recommends the use of tripod heads made of steel, aluminium or similar material. Tripod heads of fiberglass or other composite materials are not recommended.
B Tip – Trimble offers tripod part number 7072550000000 with fixed, non extendable legs. This
tripod is recommended in some regions for leveling highest order lines.
34 Trimble DiNi User Guide
Take into account that a level requires sufficient time to adjust to the ambient temperature. The following rule-of-thumb for a high precision measurement applies: Temperature difference in degree Celsius (°C) x 2 = duration in minutes required for the instrument to adjust to the new temperature.
Avoid sighting across fields with intense irradiation by sun light, e.g. at noon.
Setup and Coarse Centring
In order to guarantee the stability of measurement we recommend the use of a Trimble tripod.
Setup and coarse centring Extend the tripod legs (1) to a comfortable height of observation and fix them using the tripod locking screws (2). Screw the instrument centrally to the tripod head plate (3). The tribrach screws (4) should be in mid-position.
Trimble DiNi User Guide 35
Coarse Centring (Only When Required)
Set up the tripod roughly above the station point (ground mark). The tripod head plate (3) should be approximately horizontal.
Hook the plumb line (5) into the retaining screw and set up the tripod roughly centred above the ground mark.
Leveling and Fine Centring
Levelling andd fine centring Level the circular bubble (6) by adjusting the length of the tripod legs (1).
Precision leveling Align the control unit parallel with the imaginary connecting line between two tribrach screws. Level the instrument in the telescope axis (1) and rectangularly to it (2) by means of the tribrach screws. For checking, turn the instrument round the vertical axis in the diametrical position. In any case, the residual inclination should be within the working range of the compensator (± 15´) after having centred the circular bubble.
36 Trimble DiNi User Guide
Fine Centring (Only When Required):
Shift the tribrach on the tripod head plate until the plumb line is hanging centrally above the ground mark; repeat the leveling various times, if necessary.
Visual field DiNi® Focusing the Cross Hairs:
Sight a bright, evenly coloured surface and turn the telescope eyepiece until the line pattern is sharply defined.
C WARNING – Sighting of the sun or strong light sources must by all means be avoided because
it would cause irreparable damage to your eyes.
Focusing the Target Point:
Turn the telescope focusing control unit until the target point is sharply defined.
B Tip – Check the telescope parallax: If you move your head slightly whilst looking through the
eyepiece, there must be no relative movement between the cross hairs and the target; check focusing, if necessary.
C WARNING – Residual inclinations of the line of collimation remaining after having centred the
circular bubble are eliminated by means of the compensator. But it does not compensate any inclinations caused by insufficient adjustment of the circular bubble or of the line of collimation. For this reason, both adjustments have to be checked.
Switching the Instrument On and Off
To switch the instrument on or off press the p on/off key.
Operating the OFF function unintentionally does not lead to a loss of measured values. The system will ask in case of certain functions, but on principle, all current values (line leveling) are saved in a non-volatile working memory.

Line Adjustment (For Instrument Type 0.3mm/km Only)
In line leveling, a line is linked to points with known heights at the beginning and at the end so that the measured height difference can be compared with the nominal height difference.
The "line adjustment" program allows to spread the occurring difference over the individual staff stations proportionally to the sighting distances, obtaining adjusted heights as result. During this operation, the measured values (staff readings, distances) are not changed. Intermediate sights are only improved according to the improvement of the respective instrument station.
Line adjustments can only be performed if the leveling line has been completed and saved on the memory along with the intermediate heights.
It may happen that the definite heights of backsight points are not yet known when the line is measured. In this case, the nominal height values can be entered during the line adjustment. It is also possible to adjust loops. Loops are leveling lines with identical start and end height.
Requirements for a line adjustment: The entire leveling line has to be recorded in one project.
Set in any case the recording mode RMC.
Otherwise line adjustment will not be possible, as in the project no space is
reserved for the adjusted heights.
While measuring a station, the leveling line must not be interrupted in such a way that measurements are skipped.
The common adjustment of successive partial lines is only possible if they are linked by the "continue line" option.
But they can be positioned in chronological order at different spots in the project. Different partial lines started in each case with "new line" can only be adjusted separately.
Line adjustment does not include averaging between fore and back reading.
Line adjustment cannot be repeated.
Before starting line adjustment, make sure the battery is sufficiently charged.
The data stored on memory must not be changed between line measurement and line adjustment.
(Before line adjustment is actually started, the leveling line is checked by recalculating the measured line. The program accepts the following differences between original and recalculated values: 88 Trimble DiNi User Guide

6 Measuring Function
Measuring Principles and Components
DiNi height measurement
The method of single interval measurement is used to determine the height value (comprising a code and interpolation value) on the basis of 15 two-centimetre intervals of the staff and to average the results. For perfect recognition of the intervals and the coded information which they contain, it is essential that the staff image be accurately focused on the instrument cross-hairs. The usual fluctuations in focusing does not influence the measurement result.
DiNi distance measurement
In the DiNi, the distance to the staff is computed together with the determination of the height. This distance is the horizontal distance between the vertical axis of the instrument and the plane of the graduation of the staff (not the centre of the staff base).
Staff section in the leveling mode
For the determination of heights and distances on the DiNi, the instrument only requires a 30 cm staff section positioned symmetrically to the sighting axis. To ensure optimum measurement results, this staff section must be free from interruptions. Normally this can be easily checked in the eyepiece. For sighting distances of less than 14 m, however, a staff section larger than the visible one is evaluated. If the staff section is interrupted (e.g. by branches) or if measurements are taken beyond the base or top of the staff, the evaluated staff section is no longer symmetrical to the sighting axis.
Since major asymmetries may impair the measuring accuracy, measurement is blocked if obstacles cover more than a few centimetres beyond the cross-hairs (error message: "out of measuring range"). For distances between the minimum sighting distance and a few meters, the instrument only requires a staff section of 10 cm. Due to this minimum measuring section, a range of approx. 6 cm from the beginning and end of the staff is not read for the shortest sighting distance. Staff code
The staff code consists of 2 cm intervals filled white (yellow) / black or half white (yellow) / half black. For height and distance measurements, only the edges of the 2 cm intervals are used. Thus, necessary controls of invar staves are made easy. The precision code consisting of 1 mm wide lines is only used for decoding purposes in case of sighting distances of less than 6 metres.
94 Trimble DiNi User Guide
Measuring Function 6
Pendulum stop
If the pendulum is at its stop, measurement cannot be started. If the pendulum reaches its stop in the measuring process, the measurement is stopped and error message "compensator out of range" is displayed.
Light conditions
Direct solar irradiation in the telescope must be avoided as this may be harmful to the eye and may cause failure of the measurement. If sun reflections are visible in the telescope (sun low on horizon), shade the telescope with your hand until the reflections disappear. In the case of sun reflections on the staff, turn the staff sideways until the reflections are no longer visible to the observer. strong light If measurements are performed against strong light, the measuring time may be increased and the accuracy of the measured data may be reduced. variation in brightness / overexposure If variations in brightness during the measuring process lead to overexposure of individual measurements (the sun comes out) , the measurement is automatically restarted. If this situation occurs repeatedly, measurement is stopped with error message "Change in brightness too great".
It can then be started again. twilight / insufficient illumination If the measuring signal in twilight is too weak for reliable measurement, if the staff section available is not sufficient for measurement or if no staff has been sighted, error message "Staff cannot be read" is displayed. If the brightness is just about sufficient for measurement, the measuring time may be markedly increased. Should the resulting measuring times exceed 5 seconds, reduced accuracy of the measured data must be expected. In such cases, it is advisable to illuminate the staff. staff illumination If the staff has to be illuminated, we recommend to use a fluorescent lamp installed laterally in front of the staff beside the graduation. If the lamp is placed approximately at the height of the line of sight, a 10 W lamp (12 V, 220 V) will do. Directional light, e.g. by using an accumulator lamp, is not recommendable due to inhomogeneous illumination, formation of shadows or reflexes which could lead to errors of measurement.
Measuring beam interruption In sunlight, a short interruption of the measuring beam is of virtually no importance, due to the short exposure times. If the measuring beam is interrupted by traffic and measurements are lost, the measuring time will be extended accordingly. Trimble DiNi User Guide 95
6 Measuring Function
The displayed reading is a mean value obtained from several measurements. In the case of major differences between the individual measured values, the measurement is rejected and error message "Standard deviation out of range" is displayed. This only eliminates gross errors; an assessment of the quality of the measured data is not made. In the case of vibrations or air turbulences, it has been found that the measurements displaying the smallest deviations need not necessarily provide the best measured data.
Multiple Measurement
We recommend to use the multiple measurement option in such cases. Avoid triggering a measurement in moments of strong vibration, e.g. when a heavy vehicle is passing. This can be visually checked.
5 m telescopic staff DiNi instruments provide measurements with DiNi code staves of up to 5 m length. For this, the 5 m telescopic staff Td 24 and TD 25 are available. For the measurements all staff sections below the measured height value must be slid out and locked. If you take measurements with the staff being pushed in either partially or completely, for example as you do not need the full length of the staff, make sure not to sight at the pushed in section of the staff. Otherwise, erroneous measurements or nonsensical results cannot be precluded.

Hints for Precision Measurements
A digital level is an optical level with automatic data logging, data storage and data processing. For this reason, the marginal conditions to be observed when using a digital level are the same as with an optical level.
Hints for Precision Leveling
Do not expose tripod and instrument to one-sided irradiation by sun light. Avoid sighting across fields with intense irradiation by sun light, e.g. at noon. Take into account that also digital levels require sufficient time to adjust to the ambient temperature. The measurement applies: Temperature difference in Kelvin x 2 = duration in minutes required for the instrument to adjust to the new temperature. For measurements of normal accuracy, e.g. using foldable staves, at least half the above duration should be considered for temperature adjustment.
The DiNi instruments are equipped with a temperature sensor. The temperature gradient of the line of sight of the instrument is determined and stored by the factory. The instrument carries out the necessary improvement of the line of sight immediately during the measurement. This correction is only possible in instruments completely adjusted to the ambient temperature and, consequently, does not make the temperature adjustment unnecessary.
Equal sighting distances shall by all means be kept to eliminate possible variations of the line of sight by temperature, mechanical stress and instrumental effects (focusing lens).
Do not choose sighting distances that are considerably longer than 30 m.
To obtain the specified accuracy of the instrument and eliminate the residual compensator error, make sure the circular level has been adjusted well and apply one of the following methods for measuring: Measurement according to an alternate method, known as "red trousers" method (BFFB,FBBF) Measurement according to a non-alternate method (BFFB,BFFB) after measuring B,F, readjust the circular level with orientation to foresight.
Before triggering a measurement, make sure that vibrations and shocks transmitted to the instrument e.g. from passing heavy vehicles or strong gusts of wind have settled (check by viewing through telescope or decide by experience). Use selectable and automatic controls during Line leveling. These warnings offer the possibility to repeat or use the readings. Under all these circumstances the reading may still be possible, but these tests offer the user the possibility to ensure the highest accuracy in the appropriate application.
A warning can be set to avoid measurement to the lowest part of the staff (ground refraction).
Trimble DiNi User Guide 97
6 Measuring Function
A warning can be set to avoid measurement to the upper part of the staff. This feature is only recommended for highest precision in case of permanent measurement at the upper end of the staff (e.g. in a tunnel).
A check can be made to ensure that a full 30cm of the staff is visible, equally spaced around the horizontal cross hair. This feature is only recommended for highest precision in case the 30cm section may be partially obscured by obstuction.
Underground, Staff Sinking Into the Ground, Vertical Positioning,
Turning
similar to optical levels.
Invar Staves
On request there is a staff certificate, which describes the staves. The staves have to be used, transported and stored properly and to be calibrated in corresponding time intervals. Hints for Precision Measurement - Area Leveling
For precise area leveling, the adjustment of the line of sight is of great importance due to the different sighting distances. In line leveling, the possible inclination of the horizon is eliminated by equal sighting distances. For precise area leveling, the adjustment of the instrument prior to the measurement is absolutely advisable. In measurements carried out throughout the day, with great temperature differences between the beginning and end of measurements and additionally strong irradiation by sunlight, the internal temperature correction system of the instrument eliminates the main part of the variations of the line of sight. But to make sure, comparison measurements to fixed points should be made and readjustments should be carried out in between, if necessary.

The Type Identifier in the M5 Format
In the course of the time, requirements on the data format have increased. Therefore, the M5 Format carries most of the type identifiers of all available formats, always based on the preceding format.
Type identifiers are defined by two characters (except for Adr). If only one character is necessary, the second character is a blank.
In the M5 Format there are 5 Type identifiers (TK) defined: TK1: Adr Identifier address (Value1) TK2: T2 Identifier information (Value2) TK3: T3 Identifier 3. Value field (Value3) TK4: T4 Identifier 4. Value field (Value4) TK5: T5 Identifier 5. Value field (Value5) "KD" for point identification, "TO" for text information, "R", "HD", "Z" for T3, T4, T5.
Definition of the Type Identifiers
Type identifiers are assigned to the 5 measuring data blocks of pre-set codes, which show the number or character value of the block.
Type identifiers are (except for Adr) defined with two characters. If only one character is necessary, the second character is blank. The code is case sensitive.

8 Adjustment
Adjusting the Line of Sight
The instrument adjustment defines the necessary corrections for the line sight of DiNi, which are required to ensure optimum measuring accuracy. Increased strain placed on the instrument by extreme measuring conditions, transportation, prolonged storage and major changes in temperature may lead to misalignment of the instrument and faulty measurement results, particularly in case of different distances from instrument to staff. Adjusting the line of sight and defined measurement methods eliminating these errors.
Calling up the Adjustment Function

The old adjustment value and information are displayed.

Divide this distance into three and define 2 instrument stations (1,2) about 15 m away from the rods on the connecting line between them. Measure both rods from each of these stations.
Trimble DiNi User Guide 131
8 Adjustment
Define a distance of approx. 45 m length and divide it roughly into three. Create an instrument station (1,2) at either end and set up a staff at each point marking one third of the connecting line (A,B). Measure both rods from each of the instrument stations.
Set up 2 rods (A, B) roughly 20 m apart. First measure these rods from instrument station (1) located midway on the connecting line between the two rods. Then repeat the measurement from instrument station (2) which is located on the elongation of the two staff stations approx. 20 m outside the defined distance. Kukkamäki method 132 Trimble DiNi User Guide
Adjustment 8
This method is largely identical with the Kukkamäki method. With this method, however, the distance between the rods should be about 30 m with station (2) being about 3 m behind staff A.
Making the Adjustment
C CAUTION – Before starting any adjustment, allow the instrument to adapt to the ambient temperature and make sure it is protected against heating up on one side (sun radiation).
C CAUTION – After the selection of the adjustment method, you can change the settings of earth curvature and refraction. This is not possible at another point of the DiNi menu system. Changes of earth curvature and refraction settings become effective only if you adjust the system afterwards. The line of sight will then be corrected accordingly.
It may become necessary to correct the staff reading for earth curvature, if you must
take measurements with different sighting distances and correction is not provided by
the evaluation program used. General application of refraction correction is
controversial. It is, however, possible on DiNi instruments. You can change the
coefficient of refraction in the Input menu. If you set the coefficient to zero, the
correction of refraction will be inactive.
Select the method of your choice. In this example we will show the Förstner method.

after this procedure.
Various adjustments of lines of sight carried out successively should differ only by some seconds. Prerequisites for reaching this result are stability of installation and unchanged environmental conditions. We recommend to prepare a set of chronological statistics including the adjustment values. In case of inexplicable differences within short periods, provided the measuring conditions remained unchanged, a workshop should be consulted.

Check the Function of Circular Bubble
Automatic alignment of the compensator ensures that an inclined line of sight is automatically leveled within the working range both for visual observation and internal electronic measurement. When turning the instrument round the vertical axis, the circular bubble has to remain within the adjustment circle. In precision measurements, the running centre of the circular bubble has to be in the centre of the adjustment circle. In case of any visible change readjustment is required.
Level the instrument with the 3 tribrach screws until the circular bubble runs centrally to the adjustment circle.
Circular bubble check step 1 By turning the instrument 180° round the vertical axis the circular bubble has to remain within the circle Circular bubble check step 2 If the circular bubble left the adjustment circle it is necessary to adjust the circular level. 136 Trimble DiNi User Guide

Basis of Calculation for Line Adjustment
Line adjustment is always based on the measured and computed data recorded during leveling line measurement. Before the line adjustment, it is possible, however, that you enter the reference heights (start/end), if they had not been known in the measurement.
142 Trimble DiNi User Guide
The heights of staff stations in line leveling and those of intermediate sights are modified proportionally to the passed distance as follows. For station n, the following equations apply: Intermediate sight: Number of station Sighting distance Backsight distance Foresight distance Intermediate sight distance Total of all backsight distances of the line Total of all foresight distances of the line Line closing difference Uncorrected height of foresight Uncorrected height of intermediate sight In the project, the values of Zfu or Ziu are overwritten by Zf or Zi.
