Note:
1) The battery operating time will vary depending on the environmental conditions, such as ambi ent temper ature, chargin g time, and t he number of tim es charging and discharging the battery.
2) In low temperature (especially while the heater of display is working), the battery operating time will shorten to one-half of normal temperature use.
3) The indicator for battery power remaining shows the power level during each measurement mode. The condition indicated for the battery power remaining in the angle measurement mode may not be adequate to measure a distance. Changing from angle mode to distance mode during a poor battery condition may cause the EDM not to measure a distance. We recommend that you check the battery condition before going into the field.
4) Also note, when changing from one measurement mode to another, the battery indicator may not show a decr eas e or an i ncr ease i mm ediately. The batt ery i ndicator syste m was desi gne d to show the general condition for the battery strength. It does not respond instantly.

2.11 Inclination of Prism and Measuring Error

For the best results, aim or point prism s in the di recti on of the GTS-820 A series so t hat maximum signal can be returned to the instrument. Sighting prism obliquely because of inclined settings, may result in measuring errors. These errors will be proportional to the misalignment as showing in following graphs. The more misali gnment of the prism, the more error in me asurement. Measured data can be different according to the prism constant value. This can occur when a prism is moving. Pin- pole prism set L1 ( for one-person surveying) and pin-pole pris m holder L1 (for fixed point observation) are designed to minimize measuring error in such case. Make the best use of them. In case you are forced to use the normal prism in inclined state because there is no other way possible, we recommend to use switching holder, prism constant value (0 or 30mm), and set to 30mm (Compensation value of -30mm).

3.3 Range of Laser for Auto-tracking and Auto-collimating

The range of laser at the long di s tance is wi thin ±30' as shown i n following. So you had better collimate the prism so that the prism may be located within this range of laser in the first step. As for it, rapid automatic collimating and automatic tracking becomes possible. If the target prism is out of this range,
time for searching mode will be necessary.
Field of view

Range of laser

8.2.3 Password Option

Establishing a Password
A passwo r d can be set in th e GTS-820A series to secure the use of the instrum ent. Once a password is establi she d the user can disable the option or c hange the p assw ord . Once a pa ssw ord est a bl ish ed and the option is turned off, the password will always remain in memory. When turning on the instrument after a password-input scree n appe ars befor e the se lf -test mode. Typ e in you r pass wor d and press the [ENTER] to continue. A maximum of 10 numeric digits can be entered for a password. All zeros (0000000000) or 9`s (9999999999) are invalid passwords. If 10 unsuccessful attempts are made to input a password, the instrument will shut off automatically.

9.1 Checking and Adjusting of Ins tru ment Constant

Normally, the instrument constant does not have discrepancy. It is recommended you measure and compare with an accurately measured distance at a location where the precision is specifically monitored on a consistent basis. If such a location is not available, establish your own base line over 20m (when purchasing the i nstrument ) and compare with the data measured wit h newly purchase d instrument. In both cases note that the setu p displacement of the instr u me nt posi tion over the point, the pri sm, baseline precision, poor collimation, atmospheric correction, and correction for refraction and earth curvature determine the inspection precision. Please keep in mind these points. Also, when providing a base line in a building, please note that the difference in temperature greatly changes the length measured in the building. If a difference of 5mm or over is the r esult from the comparative measurement, the following procedure as shown below could be used to change the instrument constant.
1) Provide point C on a straight line, connecting straight line AB which is almost horizontal and about 100m long, and measure straight lines AB, AC and BC.
A
C
2) Obtain the instrument constant by repeating 1) above several times. Instrument constant=AC+BC-AB
3) When there is error between written instrument constant value and calculated value, review the Section 9. 7 “How to Set the Instrument Consta nt Value” procedure.
4) Once again, measure at a calibrated baseline and compare with the instrument base line the length.
5) If using above pr o cedu r e a nd no difference is fou nd f ro m the instrum ent const ant at the factory or a difference of over 5mm is found, contact TOPCON or your TOPCON dealer.
