model 3175
1.
Power ON the instrument while holding the MODE button down.
2.
Release both buttons at the same time and wait for calibration instructions to appear on
screen. You will have to select the direction of calibration change.
3.
Use the right SELECT button, following the chart, to access the X axis for calibration .
Please record the three-digit number that appears in the LCD the first time you enter the axis
calibration menu; this number is the factory setting (i.e. 510), to which you can return if
necessary (this number may vary anywhere between 430 and 590).
You must raise or lower the beam to center between positions A and B(Position C) on the wall. The
instrument will react to “+” and “–” input within the X+ quadrant.
If B is below A, increase the number (”+”).
If B is above A, decrease the number (“–”).
4.
Press the MODE Button to exit the X axis calibration menu, and save any changes to the
calibration settings by turning off the instrument (“QUIT”).
You must now repeat the peg test to insure you have made the correct calibration. A peg test can
be done in Calibration Mode.
Upright Position Peg Test and Calibration – Y axis (All models)
To test the Y axis, mount the instrument on a tripod and place approximately 100 feet (30m) away
from the target, with the control side (Y+ quadrant) facing the target (Fig. 18); follow steps 2 thru 4
of "
Upright Position Peg Test – X axis
". Calibrate as in "Upright Position Calibration – X axis",
choosing the
Y axis
to calibrate and adjusting “+” and “–” input as necessary within
the Y+ quadrant.
Note: In the model 3110-GR, in order to calibrate the Y axis, when the Manual and ADS LED’s flash
to indicate that you entered the Calibration Mode, press the Manual button in order to turn off the
corresponding LED.
If you are unable to calibrate the instrument, or if the difference between positions A and B is too
great to calibrate within the numerical range of 430 to 590, please contact David White or an
authorized service center for assistance.
Laydown Position Peg Test – Z axis (3150, 3175 only)
1.
To test the Z axis, place the instrument on its back using the built-in trivet (control panel
facing upward), 100 feet (30m) from a wall on a flat, level surface.
2.
Hang a plumb line down the wall at least 8 feet long (2,5 m).
