NOTE:
If movement occurs in only the grade axis, ADS may not indicate movement since the
movement is being detected by the non-grade (level) axis. However, in a real world application,
both the grade and level axis will likely move.
Line Position Mode (Model 3150 and 3175)
In this mode, the instrument allows you to fine-tune the location of your vertical (plumb) laser line.
For example, if you’ve established a plumb line and find that the line is slightly off to the left or right
of your target, use Line Position to jog the line into place without moving the entire instrument
(useful for floor and wall tile installation, walls or partitions, etc.). The laser will now remain aligned
to your target even if you enter other modes (Rotation, Spot, Point-to-Point)
model 3150
Line Position mode is available when the instrument is placed in the plumbing position (control
panel facing upward). While the instrument is in the plumbing position, it can be used in Rotation,
Sweep or Spot mode. To enter the Line Position mode and position the laser reference point the
instrument must be rotating. Use the “
F
” or “
G
” buttons to position the laser reference point while
the instrument is rotating ( Fig. 13). If the instrument is in Spot or Sweeping mode the “
F
” and “
G
”
buttons are used to move the spot or sweep clockwise and counterclockwise, as they do when
the laser is in the upright position.
NOTE:
The LEFT and RIGHT buttons of the RC700 Remote can be used to position the reference line
regardless of the instrument being in Rotation, Spot, or Sweep Mode.
If in manual mode , the LEFT and RIGHT buttons will position the reference line and the UP and
DOWN buttons will move the vertical line up and down
model 3175
Line Position mode is available when your instrument is placed in the
plumbing position (control panel facing upward). While the instrument
is in the pluming position, it can be used in Rotation, Spot, or Point-to-
Point mode. To enter Line Position mode, use the Mode button to go to
the Line Position option and press select. The instrument will rotate at
the last rotation speed selected. Press the SELECT buttons to move the position of the laser
reference point clockwise (right) or counterclockwise (left) into perfect alignment with your target.

REPLACING BATTERY
For models 3110-GR and 3150, if the battery is low, the red light (only) is illuminating on the front of
the instrument.
For model 3175, if the battery is low, the LCD will display “ERROR BATTERY LOW”.
If the instrument operates erratically, try replacing the batteries. (Fig.15)
1. Remove the battery tray by unscrewing the plastic nut around the mounting thread
on the bottom of the instrument.
2. Remove the old batteries and replace with 4 new “D” cell Alkaline batteries.
