4. The adjustments are automatically saved.
You must now repeat the peg test to insure you have made the correct calibration. A peg test can
be done in Calibration Mode.
Model LMH600
1. Power ON the instrument while holding the (G) button. You will know if Calibration Mode is
activated when the (3) and (2) LEDs flash alternately.
2. The (K) and (J) button change the X-axis increments. The (J) button will produce a
positive (+) increment (the (H) and (I) will change the Y-axis. The (H) button will
produce a positive (+) for Y, and the and the (I) button will produce a negative(-)
increment.(Fig.17)
3. You must raise or lower the beam to center between positions A and B on the target. The
instrument will react to "+" and "–" input within the X+ quadrant. The instrument DOES NOT
react to adjustments until the instrument is forced to re-level (i.e. rotate and re-check point A).
If B is below A, increase the increment (+).
If B is above A, decrease the increment (-).

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 LMH-CU, in order to calibrate the Y axis, when the Battery and ADS LED's flash
to indicate that you entered the Calibration Mode, press the ADS button in order to turn OFF the
corresponding LED.
Laydown Position Peg Test – Z axis (LMH600 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 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.
