Upright Position Peg Test And Calibration - Y Axis (All Models) - CST/BERGER AL Serie Manual De Instrucciones

If B is below A, increase the increment (+).
If B is above A, decrease the increment (-).
5. The adjustments are automatically saved when the ON/OFF button is pressed.
6. 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 ALH, 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 CST/berger or an
authorized service center for assistance.
Laydown Position Peg Test – Z axis (ALHV, ALHV-G, ALGR 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).
3. Press the (A) button ("POWER" in the ALGR) and allow the instrument to self-level. If
necessary, adjust the rotation speed to easily view the laser beam on the wall. Orient the
instrument parallel to the wall and attempt to align with your plumb line. (Fig.19)
If the laser line does not align with the plumb line, then calibration is necessary.
Laydown Position Calibration – Z axis (ALHV, ALHV-G, & ALGR only)
Keep the instrument in its current position. Power OFF the instrument.
model ALHV, and ALHV-G
1. Power ON the instrument while holding the (C) button down. You will know if Calibration
Mode is activated when the Manual Mode and Anti-Drift LEDs flash alternately.
2. The (D) and (F) button change the axis increments. The (D) button will produce a
positive (+) increment.
3. Select the (D) button to rotate the laser beam counterclockwise, or the (F) button to rotate
the laser beam clockwise into alignment with your plumb line.(Fig. 19) For example, the beam
must rotate counterclockwise to align with the plumb line, so you must select the (D) button.
4. The adjustments are automatically saved.
