if needed.
N N o o t t e e : In Sweep or Point-to-Point Mode, the selected sweep area

Spot Mode (Models 3150 and 3175)
Spot Mode creates a motionless laser dot for reference, allowing the instrument to be used as a
straight-line laser.
model 3150
Press the (E) button untill the laser is in Spot Mode. Press the (F) or ( G) to rotate the laser head
clockwise or counter-clockwise. Pressing and holding the (G) or
(F) button moves the rotating beam more quickly.
model 3175
Use the SELECT buttons to rotate the position of the dot
clockwise or counterclockwise.
Re-Leveling (Models 3110-GR and 3150)
If the instrument is bumped or moved, the instrument will automatically attempt to re-level itself.
On a job site, it may be necessary to prevent re-leveling in order to prevent inaccurate
measurements by the operator. The Anti-Drift System (ADS) is used for this purpose (see Anti-Drift
System - ADS). The instrument can also be placed in Manual Mode to allow the instrument to
continue operating when out of level.
Axis Drive Error (Models 3110-GR and 3150)
If the laser is set up or tipped beyond its self-leveling range of ±5°, the laser head will initially
attempt to level; however, when the self-leveling limit is reached, an error will indicate an axis
error (Fig. 8).
Turn the instrument OFF, move the instrument to a more level position, then turn the instrument
on again.
Model 3175
The display shows "X TOO STEEP or Y TOO STEEP" Turn the instrument OFF, move the instrument
to a more level position, then turn the instrument on again.
If the instrument continues to poduce errors, contact David White®-Customer Service.
