Calibrating the Angle Sensor
This Laser Distance Meter is equipped with highly accurate digital
angle sensors for using the 1-Point Pythagoras measurement mode.
This sensor should be calibrated regularly for the most accurate
results possible.
To calibrate the angle sensor:
1. Find a fairly level horizontal surface such as a countertop, desk,
wood floor, etc. The surface does not need to be perfectly level but
should be within approximately 2° of level.
2. With the Laser Distance Meter powered off, hold down both the
button and the button simultaneously.
3. Release the button.
4. When “CAL0” appears on the screen, release the button.
5. With “CAL0” on the screen, position the Laser Distance Meter
upright on the surface so that the laser beam is pointing towards
the sky and the screen is facing you.
6. Press the button and then release the Laser Distance Measure
so that it is balancing vertically in an upright position. On the screen,
“CAL0” will change to “CAL 1”, followed by “OK.”
7. Rotate the Laser Distance Meter 180 degrees so it is upright with
the laser beam pointing towards the sky and the screen is facing
away from you.
8. Press the button. “CAL 2” will appear on the screen followed
by “OK.”
9. Lay the Laser Distance Meter down so that the laser beam is facing
away from you and the screen is facing the sky.
