Description
This manual applies to Zoom20 A4, Zoom20 Pro, Zoom30 Pro and Zoom35
Pro instruments. Where there are differences between the instruments they are clearly described.
The appearance of the products is subject to change without notice. The appearance of the actual product may vary slightly from the product shown in the illustrations.
• Measuring with IR modes: When measuring distances to a reflector with Electronic Distance Measurement (EDM) mode "IR", the telescope uses a wide visible red laser beam, which emerges coaxially from the telescope's objective.
• Measuring with RL modes: Instruments that are equipped with a reflectorless EDM additionally offer the EDM mode “Reflectorless (RL)”.
When measuring distances with this EDM mode, the telescope uses a narrow visible red laser beam, which emerges coaxially from the telescope's objective.
WARNING

Distancer, Measurements without Reflectors (Reflectorless mode)
The EDM module built into the product produces a visible laser beam which emerges from the telescope objective.
The laser product described in this section is classified as laser class 3R in accordance with:
• IEC 60825-1 (2014-05): "Safety of laser products"
Direct intrabeam viewing may be hazardous (low eye hazard level), in particular for deliberate ocular exposure. The beam may cause dazzle, flash-blindness and after-images, particularly under low ambient light conditions. The risk of injury for laser class 3R products is limited because of: a) unintentional exposure would rarely reflect worst case conditions of (e.g.) beam alignment with the pupil, worst case accommodation, b) inherent safety margin in the maximum permissible exposure to laser radiation (MPE) c) natural aversion behaviour for exposure to bright light for the case of visible radiation.

From a safety perspective, class 3R laser products should be treated as potentially hazardous.
Precautions:
1) Prevent direct eye exposure to the beam.
2) Do not direct the beam at other people.
Potential hazards are not only related to direct beams but also to reflected beams aimed at reflecting surfaces such as prisms, windows, mirrors, metallic surfaces, etc.
Precautions:
1) Do not aim at areas that are essentially reflective, such as a mirror, or which could emit unwanted reflections.
2) Do not look through or beside the optical sight at prisms or reflecting objects when the laser is switched on, in laser pointer or distance measurement mode. Aiming at prisms is only permitted when looking through the telescope.

Direct search
Pointsearch
Pointsearch is a function used by programs to find measured or known points in the memory storage.
It is possible to limit the point search to a particular job or to search the whole storage. The search procedure always finds known points before measured points that fulfil the same search criteria. If several points meet the search criteria, then the results are ordered according to the entry date. The instrument finds the most recent known point first.
By entering an actual point number, for example 402, and pressing SEARCH, all points within the selected job and with the corresponding point number are found.
Wildcard search
Examples of point searches
SEARCH
To search for matching points within the selected job.
The wildcard search is indicated by a "*". The asterisk is a place holder for any following sequence of characters. Wildcards should be used if the point number is not fully known, or to search for a batch of points.
* All points are found.
A All points with exactly the point number "A" are found.
A* All points starting with "A" are found, for example, A9, A15, ABCD, A2A.
*1 All points containing only one "1" are found, for example, 1, A1, AB1.
A*1 All points starting with "A" and containing only one "1" are found, for example, A1, AB1, A51.

Operation
Instrument Setup
This topic describes an instrument setup over a marked ground point using the laser plummet. It is always possible to set up the instrument without the need for a marked ground point.
Important features
• It is always recommended to shield the instrument from direct sunlight and avoid uneven temperatures around the instrument.
• The laser plummet described in this topic is built into the vertical axis of the instrument. It projects a red spot onto the ground, making it appreciably easier to centre the instrument.
• The laser plummet cannot be used with a tribrach equipped with an optical plummet.
When setting up the tripod pay attention to ensuring a horizontal position of the tripod plate. Slight corrections of inclination can be made with the foot screws of the tribrach. Larger corrections must be done with the tripod legs.
a
Loosen the clamping screws on the tripod legs, pull out to the required length and tighten the clamps.
a) In order to guarantee a firm foothold sufficiently press the tripod legs into the ground. b) When pressing the legs into the ground note that the force must be applied along the legs.
b
Careful handling of tripod.
• Check all screws and bolts for correct fit.
• During transport always use the cover supplied.
• Use the tripod only for surveying tasks.

Level up with the electronic level step-by-step
4
The electronic level can be used to precisely level up the instrument using the footscrews of the tribrach.
1) Turn the instrument until it is parallel to two footscrews.
2) Center the circular level approximately by turning the footscrews of the tribrach.
3) Turn on the instrument, and, if tilt correction is set to 1- or 2-axis, the laser plummet will be activated automatically, and the Level Up screen appears. Otherwise, press FNC from within any application and select Level.
The bubble of the electronic level appears if the instrument tilt is inside a certain levelling range.
Center the electronic level of the first axis by turning the two footscrews. When the electronic level is centered, the indicator on one of the electronic bubbles is centered.
5 Center the electronic level for the second axis by turning the last footscrew. When the electronic level is centered, the indicator on the second electronic bubble is centered.
When the electronic level is centered the instrument has been perfectly levelled up.
6 Accept with OK.
Change the intensity of the laser plummet
External influences and the surface conditions may require the adjustment of the intensity of the laser plummet.
In the Level Up screen, adjust the intensity of the laser plummet using the navigation key.
The laser can be adjusted in 25% steps as required.
Position over pipes or holes
Under some circumstances the laser dot is not visible, for example over pipes. In this case, using a transparent plate enables the laser dot to be seen and then easily aligned to the center of the pipe.

Working with the Battery
Charging / first-time use
• The battery must be charged prior to using it for the first time because it is delivered with an energy content as low as possible.
• The permissible temperature range for charging is between 0°C to +40°C/+32°F to +104°F. For optimal charging we recommend charging the batteries at a low ambient temperature of +10°C to
+20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers recommended by
GeoMax, it is not possible to charge the battery if the temperature is too high.
• For new batteries or batteries that have been stored for a long time (> three months), it is effectual to make only one charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We recommend carrying out the process when the battery capacity indicated on the charger or on a GeoMax product deviates significantly form the actual battery capacity available.
Operation / Discharging
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating temperatures reduce the service life of the battery.
Change the battery step-by-step
Open the battery compartment (1) and remove the battery holder.
Remove the battery from the battery holder (2).

RL measurements
Distance Measurements - Guidelines for Correct Results
A laser distancer (EDM) is incorporated into the instruments. In all versions, the distance can be determined by using a visible red laser beam which emerges coaxially from the telescope objective. There are two EDM modes:
• Prism measurements (IR) • Reflectorless measurements (RL)
IR measurements
WARNING
• When a distance measurement is triggered, the EDM measures to the object which is in the beam path at that moment. If a temporary obstruction, for example a passing vehicle, heavy rain, fog or snow is between the instrument and the point to be measured, the EDM may measure to the obstruction.
• Be sure that the laser beam is not reflected by anything close to the line of sight, for example highly reflective objects.
• Avoid interrupting the measuring beam while taking reflectorless measurements or measurements using reflective foils.
• Do not measure with two instruments to the same target simultaneously.
• Accurate measurements to prisms should be made in IR-Default mode.
• Measurements to strongly reflecting targets such as traffic lights in Prism mode without a prism should be avoided. The measured distances may be wrong or inaccurate.
• When a distance measurement is triggered, the EDM measures to the object which is in the beam path at that moment. If for example people, cars, animals, or swaying branches cross the laser beam while a measurement is being taken, a fraction of the laser beam is reflected from these objects and may lead to incorrect distance values.
• Measurements to prisms are only critical if an object crosses the measuring beam at a distance of 0 to
30 m and the distance to be measured is more than 300 m.
• In practice, because the measuring time is very short, the user can always find a way of avoiding unwanted objects from interfering in the beam path.
Due to laser safety regulations and measuring accuracy, using the Long Range Reflectorless EDM is only allowed to prisms that are more than 1000 m (3300 ft) away.

Set Out is an application used to place marks in the field at predetermined points. These predetermined points are the points to be staked. The points to be staked may already exist in a job on the instrument, or be manually entered.
The application can continuously display differences, between current position and desired set out position.
Points can be staked using different modes: Polar mode, Orthogonal to station mode and Cartesian mode.

Measuring Information
The following measurement sequences are possible:
• Horizontal direction and vertical-angles only (resection)
• Distance and horizontal direction and vertical-angle
• Horizontal direction and vertical-angles to some point(s) and horizontal direction and vertical angles plus distance to other point(s).
Single face I, single face II, or dual face I and II measurements are always possible. No specific point sequence or specific face sequences are required.
When measuring the same target in both faces, the reflector height may not be changed when observing in the second face. Error checks are made for dual face measurements to ensure the same point is sighted with the other face.
If a target point is measured several times in the same face, only the last valid measurement is used for computation.
Target points with 0.000 height are discarded for height processing. If a target point has a valid height of 0.000 m, use 0.001 m to include it for height processing.
Computation Procedure
The measuring procedure automatically determines the method of evaluation, for example resection or three point resection.
If more than the minimum required measurements are performed, the procedure uses a least squares adjustment to determine the 3D position and averages orientation and height measurements.
• The original averaged face I and face II measurements are used for the computation process.
• All measurements are treated with the same accuracy, whether these are measured in single or dual face.
• Easting and Northing are determined by the least squares method, which includes standard deviation and improvements for horizontal direction and horizontal distances.
• The final height (Z) is computed from averaged height differences based on the original measurements.
• The horizontal direction is computed with the original averaged face I and face II measurements and the final computed plan position.
Resection Results
Press CALC. from the Sight target point screen after at least two points and a distance have been measured.
This screen displays calculated station coordinates. The final computed results are Easting, Northing and
Height coordinates of the present instrument station, including the instrument height.
Standard deviations and residuals for accuracy assessments are provided.
Target Residuals
RESID
To display residuals. Refer to "Target Residuals".
StdDev
To display the standard deviation of the coordinates and angle.
If the instrument height was set to 0.000 in the setup screen, then the station height refers to the height of the tilting axis.
Next step
Press RESID to display the target residuals.
The TARGET RESIDUALS screen displays the computed residuals for the horizontal and vertical distances and the horizontal direction. Residual = Calculated value - Measured value.

Calibration
Overview
Description
Electronic calibration
Mechanical calibration
GeoMax instruments are manufactured, assembled and adjusted to a high quality. Quick temperature changes, shock or stress can cause deviations and decrease the instrument accuracy. It is therefore recommended to calibrate the instrument from time to time. This can be done in the field by running through specific measurement procedures. The procedures are guided and have to be followed carefully and precisely as described in the following chapters. Some other instrument errors and mechanical parts can be adjusted mechanically.
The following instrument errors can be checked and calibrated electronically:
• Horizontal collimation error, also called line-of-sight error.
• Vertical index error, and simultaneously the electronic level.
• Compensator longitudinal and transversal index errors.
For determining these errors, it is necessary to measure in both faces, but the procedure can be started in any face.
The following instrument parts can be calibrated mechanically:
• Circular level on the instrument and tribrach.
• Laser plummet.
• Screws on the tripod.
During the manufacturing process, the instrument errors are carefully determined and set to zero. As mentioned, these errors can change and it is highly recommended to redetermine them in the following situations:
• Before the instrument is used for the first time.
• Before every high precision survey.
• After rough or long periods of transport.
• After long periods of work or storage.
• If the temperature difference between current environment and the temperature at the last calibration is more than 10°C (18°F).
Preparation 13.2
Before determining the instrument errors, level-up the instrument using the electronic level.
The Level & Plummet is the first screen to appear after turning on the instrument.
The tribrach, the tripod and the ground should be very stable and secure from vibrations or other disturbances.
The instrument should be protected from direct sunlight in order to avoid thermal expansion on one side only.
Before starting to work, the instrument has to become acclimatised to the ambient temperature. Approximately two minutes per °C of temperature difference from storage to working environment, but at least
15 min, should be taken into account.

Line-of-sight error
Calibrating Line-of-Sight and Vertical Index Error
The line-of-sight error, or horizontal collimation error is the deviation from the perpendicular between the tilting axis and the line of sight. The effect of the line-of-sight error to the horizontal direction increases with the vertical angle.

The vertical circle should read exactly 90° (100 gon) when the line of sight is horizontal. Any deviation from this figure is termed vertical index error. This is a constant error that affects all vertical angle readings.

a b b d a
TSOX_141 c a) Mechanical vertical axis of the instrument, also called standing axis b) Plumb line c) Longitudinal component (l) of the compensator index error d) Transversal component (t) of the compensator index error
The compensator index errors (l, t) occur, if the vertical axis of the instrument and the plumb line are parallel but the zero points of the compensator and the circular level do not coincide. The calibration procedure electronically adjusts the zero point of the compensator.
A longitudinal component in direction of the telescope and a transversal component perpendicular to the telescope define the plane of the dual axis compensator of the instrument.
The longitudinal compensator index error (l) has a similar effect as the vertical index error and effects all vertical angle readings.
The transversal compensator index error (t) is similar to the tilting axis error. The effect of this error to the horizontal angle readings is 0 at the horizon and increases with steep sightings.
1) Select Tools from the MAIN MENU.
2) Select Calib. from the TOOLS menu.
3) Select Comp. Index.

Inspect the laser plummet step-by-step
1 Place and secure the tribrach onto the tripod, and then secure the instrument onto the tribrach.
2 Using the tribrach footscrews, level the instrument with the electronic level. To activate the electronic level, turn on the instrument, and, if tilt correction is set to 1- or 2-axis, the Level & Plummet screen appears automatically. Alternatively, press FNC from within any application and select Level &
Plummet.
3 The bubbles of the instrument and tribrach levels must be centered. If one or both circular levels are not centered, adjust as follows.
Instrument: If the bubble extends beyond the circle, use the Allen key supplied to center it with the adjustment screws.
Tribrach: If the bubble extends beyond the circle, adjust it using the adjustment pin in conjunction with the adjustment screws. Turn the adjustment screws:
• To the left: and the bubble approaches the screw.
• To the right: and the bubble goes away from the screw.
4
Repeat step 3 on the instrument and tribrach until both circular levels are centered and no further
adjustments are necessary.
After the calibration, no adjustment screw should be loose.
Inspecting the Laser Plummet of the Instrument
The laser plummet is integrated into the vertical axis of the instrument. Under normal conditions of use, the laser plummet does not need adjusting. If an adjustment is necessary due to external influences, the instrument has to be returned to a GeoMax service department.
1 Set up the instrument on the tripod approximately 1.5 m above the ground and level up.
2 To activate the laser plummet, turn on the instrument, and, if tilt correction is set to 1- or 2-axis, the laser plummet will be activated automatically, and the Level & Plummet screen appears. Otherwise, press FNC from within any application and select Level & Plummet.
Inspection of the laser plummet should be carried out on a bright, smooth and horizontal surface, such as a sheet of paper.
3 Mark the center of the red laser dot on the ground.
4 Turn the instrument slowly through 360°, carefully observing the movement of the red laser dot.
The maximum diameter of the circular movement described by the center of the laser dot should not exceed 3 mm at a height of 1.5 m.
5 If the center of the laser dot makes a clearly circular movement, or moves more than 3 mm away from the point which was first marked, an adjustment may be required. Call your nearest GeoMax service centre. Depending on brightness and surface type, the size of the laser dot can vary. At a height of
1.5 m an average diameter of 2.5 mm is estimated.

Scale Correction
Use of scale correction
Atmospheric correction
Atmospheric corrections °C
By entering a scale correction, reductions proportional to distance can be taken into account.
• Atmospheric correction.
• Reduction to mean sea level.
• Projection distortion.
The slope distance displayed is correct if the scale correction in ppm, mm/km, which has been entered corresponds to the atmospheric conditions prevailing at the time of the measurement.
The atmospheric correction includes:
• Adjustments for air pressure
• Air temperature
For highest precision distance measurements, the atmospheric correction should be determined with:
• An accuracy of 1 ppm
• Air temperature to 1°C
• Air pressure to 3 mbar
Atmospheric corrections in ppm with temperature [°C], air pressure [mb] and height [m] at 60 % relative humidity.

The instrument calculates the slope distance, horizontal distance, and height difference in accordance with the following formulas. Earth curvature (1/R) and mean refraction coefficient (k = 0.13) are automatically taken into account when calculating the horizontal distance and height difference. The calculated horizontal distance relates to the station height and not to the reflector height.
