LCD display facing you and press the power button to turn the
EL30 on. Record the angle value (A) on the display.
Rotate the EL30 180° with the screen facing away from you and
record the value (B).
If A, B angle value margin exceed 0.2 degree, it is necessary to
calibrate the horizontal accuracy.
Also follow above procedure in vertical position to check vertical
accuracy
Calibration
1. Select a flat and horizontal platform as a reference
surface
2. Press the power button to turn the unit on
3. Press and hold the ZERO button until -0- is displayed on
the LCD screen. Wait 3 seconds, press the ZERO button
again the LCD will now display -1-
4. Turn the unit 180 degrees, keeping the unit on the same
horizontal platform, and wait for 3 second, then press
ZERO, the LCD will display -2-, and then will display angle
value. Horizontal calibration is now complete.
Note: all the above operation should be operated on the same
position of the same plane.
To calibrate vertical plane, repeat above procedure on vertical
