5. PREPARATION
Auto leveling
• By performing auto leveling, the center of the instrument is automatically leveled within the range
of ±30". After that, if the inclination of the main unit exceeds the range of inclination
compensation (±6'), the red LED will light up. In this case, auto leveling will not automatically
start. Perform auto leveling again.
PROCEDURE
1. Press {Auto leveling switch} while auto leveling is stopped.
The auto leveling LED starts blinking in green and auto leveling starts. After completing auto
leveling, the LED lights up in green.
• If a foreign object gets caught in the auto leveling section, hold down {Auto leveling switch}.
If the leveling screw is extended, remove the foreign object, and restart auto leveling.
The following describes how to press {Auto leveling switch} and its relationship with the
operation of the instrument:
*1)
If a sound other than these beep sound patterns is heard, refer to the instruction manual of TS-
Shield.
*2)
When auto leveling is performed by pressing {Auto leveling switch} for a long time (1 second), the
same auto leveling operation as that performed when {Power switch} is turned ON is performed.
Measurement by rotating the instrument 180° calibrates the inclination sensor.
Caution
Do not touch the instrument during auto leveling. Doing so may cause injury.
