Auto Level Mode (Model 3175)
The Auto Level Mode allows you to control how the instrument
reacts when moved out of level.
Auto Level Mode can be ON, OFF, or ADS. If Auto Level Mode is
set to ON, the instrument will
re-level if the instrument is moved out of level.
If Auto Level Mode is set to OFF, the laser will NOT re-level if the
instrument is moved out of level, and will continue to operate; use
this option when using an adapter or mount that allows you to tilt
the instrument to create a diagonal laser line. Use the left SELECT
button to turn the Auto Level option ON or OFF. You may also put
the level into ADS Mode ( see Anti-Drift System- ADS).
Anti-Drift System – ADS (Models 3110-GR
3150, and 3175)
The Anti-Drift System, when ON, will signal to the operator that the instrument has been moved out
of level.The laser head will stop rotating, and the beam and ADS LED will blink in the models
3110GR and 3150; in the model 3175 the display will show “CONT UNIT UNLEVEL”.
Models 3150, 3110-GR
The default setting for ADS is user selectable. The default setting may be set to ADS ON or ADS
OFF. When the instrument is OFF, press and hold the “
I
” button (3110-GR) or the “
G
” button (3150)
and then press the “
A
” button. Once the instrument is on, turn the instrument off for 15 sec and
then back on. If ADS was ON (OFF), it will now be OFF (ON).
To activate ADS, turn off the Manual Mode (if it is ON), by pressing “
C
” and then press the ADS
(“B”) button. If after 1 minute, the instrument is disturbed and the ADS light is flashing it is
necessary to check any bench marks that have been made and ensure the proper "HI" (Height of
Instrument). After the flashing ADS has been reset, by pressing the button one time, you will have
an additional minute to set and check your measurements.
To turn ADS off press the “
B
” button once. This will put the instrument into normal Auto
Self-Leveling mode.
