CHAPTER 3 Getting Started 3 In this chapter: Q Turning the Instrument On and OFF Q Basic Operation Total Station Nivo Series Instruction Manual 21
3 Getting Started Turning the Instrument On and OFF Turning on the instrument Press [Power] key to turn on the instrument, and the application program will start up. Refer to the operation manual for how to use the application program. Note – Check the batteries are correctly inserted into the slot if the application program doesn’t start up even after pressing [power]. Turning off the instrument Press [Power] key, and the “Power Key!” window shown on the right appears.
Getting Started 3 Basic Operation Turning on and off the Backlight Press [Power] key, and the “Power Key!” window shown on the right appears. Tapping [Backlight On/Off] button on the window switches on/off the back light. Tap [OK] button, and the window disappears. The display returns to the screen shown before pressing [Power] key. Other functions Press [Power] key, and the “Power Key!” window shown on the right appears. Press [Options] button on the window to display option menu.
3 Getting Started Cleaning of touch screen Tapping the menu button [Clean Touch Screen] disables the touch screen. Use this menu button for cleaning the touch panel. Press (Enter) key, and the display returns to the screen shown before pressing [Power] key. Adjustment of touch screen Tapping the menu button [Adjust Touch Screen] shows the touch panel adjustment window. By following the instruction in this window, a gap between the actual tapping point and button on the window will be corrected.
Getting Started 3 Shut down Tap the menu button [Shutdown], and the warning window shown on the right is displayed. Tap [Yes] button to execute Shut down. Tap [No] button to cancel Shut down and return to the screen shown before pressing [Power] key. Note – Executing Shut down completely turns off the Total Station. Note – Executing Shut down ends the application program and the data that are not stored in the program will be lost.
3 Getting Started The latest battery status is displayed. Choose [Power Off] tab. Time setting window is displayed. Check the check box of [Suspend after] in the “Idle Time Settings” field. Select time from the pull down menu. Selectable time is 5/10/30 minutes. The suspend mode check box will be cleared if time is not selected from the pull down menu. Tap [OK] button to complete the setting. Note – Suspend mode and standby mode are the same status.
Getting Started 3 Current set date and time are displayed. Set date, time and time zone. Tap [Apply] button to fix the set values. Tap [OK] button to complete the setting process.

CHAPTER 4 Checking and Adjustment 4 In this chapter: Q Adjusting the Electronic Level Q Checking and Adjusting the Circular Level Q Checking and Adjusting the Optical/Laser Plummet Q Zero Point Errors of Vertical Scale and Horizontal Angle Corrections Q Checking the Instrument Constant Q Checking the Laser Pointer Total Station Nivo Series Instruction Manual 29
4 Checking and Adjustment Adjusting the Electronic Level Adjustment of the electronic level is done by Zero point errors of vertical scale and horizontal angle corrections. For detailed instruction, please see page 31. Checking and Adjusting the Circular Level Once you have checked and adjusted the electronic level, check the circular level.
Checking and Adjustment 4. 4 If the image or laser pointer is not in the same position, adjust the optical or laser plummet: a. Use the supplied hexagonal wrench to turn the adjustment screws until the image of the X is in Position P. Position P is the center point of the line connecting the X and the center of the reticle mark . b. Repeat from Step 2. For laser plummet adjustment, a cap needs to be removed. Zero Point Errors of Vertical Scale and Horizontal Angle Corrections Checking 1.
4 Checking and Adjustment Adjusting There are two steps in the calibration program. Usually you only complete the first step that is described below, because the trunnion axis is finely adjusted mechanically. To make a major adjustment to the trunnion axis error compensation, however, you can complete the second step that is described below and make three sets of observations.
Checking and Adjustment 4 When you have taken the measurement, the message changes from DO NOT TOUCH! to Turn to F2. 2. Take an F2 measurement to the same target. Tap [OK]. VA2 HA2 Face-2 vertical angle (tilt-off value) Face-2 horizontal angle (tilt-off value) X2 Y2 Face-2 X axis tilt value Face-2 Y axis tilt value When the observation on F2 is completed, three parameters are displayed. 3. 4. Do one of the following: – To return to the first observation screen, tap [Redo].
4 Checking and Adjustment If the HA corr. setting is set to OFF, the ACH parameter is not applied to horizontal angle readings. If this setting is set to ON, both of the ACH and trunnion-axis parameters are applied to HA. If you do not complete the second step, the trunnion-axis parameter remains set to zero, and only the ACH parameter is applied. If ACV, ACH, X, or Y is out of range, OVER appears. Press any key to return to the first observation screen. Second step 34 1.
Checking and Adjustment 4 The tolerance in angle reading to each direction is 10". To maintain the accuracy of the instrument, you must take shots with extreme care. If the dHA to the same direction is more than 10", an error message appears, and you must remeasure all three sets of points. After three sets of F1/F2 observations, the instrument calculates the trunnion axis parameter and the updated ACH (the average of each set). 3. 4.
4 Checking and Adjustment Trunnion axis compensation The trunnion axis error is reported when the vertical axis and the trunnion axis (horizontal axis) are not perpendicular to each other. The sighting axis error is from the sighting and the trunnion axes. These two errors can be compensated by applying the Tr-axis and ACH parameters on this instrument to horizontal angle readings.
Checking and Adjustment 4 Checking the Instrument Constant The instrument constant is a numerical value used to automatically correct for the displacement between the mechanical and electrical centers when measuring distances. The instrument constant is set by the manufacturer before the instrument is shipped. However, to ensure the highest operational accuracy, we recommend that you check the instrument constant several times a year.
4 Checking and Adjustment Checking the Laser Pointer The Nivo series total station uses a red laser beam to a laser pointer. The laser pointer is coaxial with the line of sight of the telescope. If the instrument is well adjusted, the red laser pointer coincides with the line of sight. External influences such as shock or large temperature fluctuations can displace the red laser pointer relative to the line of sight.
