Checking and Adjusting
4.1.2 Horizontal Calibration
)
•
The laser must be calibrated to bring beam to the center of the two marks
(Steps 3-4 in "4.1.1 Horizontal Checking").
•
The calibration is easily done using the laser keypad or the ZDR300 in
remote control mode.
X-axis calibration
1. Turn the laser off before switching to calibration mode. Simultaneously
press two laser keys, On/Off and auto/man.
2. After a few seconds, release On/Off key.
3. The X LED indicator (19) will blink, then the Y LED (21). Release the
auto/man key.
4. The X LED (19) will blink rapidly, indicating the laser is ready to be cali-
brated in the X-axis. If you have not moved the laser, use the X marks
made in Steps 3 and 4 of "4.1.1 Horizontal Checking".
5. Mark the spot that's halfway between the two marks.
6. With X1 facing the marks, bring the laser beam up or down to the center
mark by using (16) or (17) on the laser keypad or (2) or (3) on the
7. Next, check Y-axis against center mark. Turn the laser 90° so that Y1 faces
the wall. If the beam is not on the center mark, calibrate Y. If Y is OK, see
"Saving the calibration" below.
