6 Tools 6.1 Calibration 6.1.1 Overview Description 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.
☞ 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. 6.1.3 Calibrating Line-of-Sight, Vertical Index Error and Compensator Index Error Line-of-sight 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.
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.
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 levels are centered and no further adjustments are necessary. ☞ After the calibration, no adjustment screw should be loose. 6.1.
☞ 5 6.1.6 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. If the center of the laser dot makes a clearly circular movement, or moves more than 3mm away from the point which was first marked, an adjustment may be required. Call your nearest GeoMax service department. 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.

Use it only within the specified temperature range.
8 Care and Transport 8.1 Transport Transport in the field When transporting the equipment in the field, always make sure that you • • • either carry the product in its original transport container, or carry the tripod with its legs splayed across your shoulder, keeping the attached product upright. or remove product from tripod and carry it by its handle. Transport in a road vehicle Never carry the product loose in a road vehicle, as it can be affected by shock and vibration.
Damp products Dry the product, the transport container, the foam inserts and the accessories at a temperature not greater than 40°C/104°F and clean them. Remove the battery cover and dry the battery compartment. Do not repack until everything is dry. Always close the transport container when using in the field. Cables and plugs Keep plugs clean and dry. Blow away any dirt lodged in the plugs of the connecting cables.
