Calibrating the Digital Level
This section describes how to calibrate the Pro 3600 digital level.This procedure re-calibrates the level
through its entire 360 degree range by recording four horizontal and four vertical settings. You should
perform this procedure whenever the accuracy test shows a variance larger than ±0.1 degree.
Follow this procedure to calibrate the digital level:
1 Turn on the level by pushing the ON/OFF button. Place the level on a flat surface free of dust or debris.
You can use any horizontal surface within 10 degrees of level and any vertical surface within 10 degrees
of plumb to perform the calibration. You must use the same surface(s) throughout the entire calibration
process. If at any time the calibration process fails or will not continue, you can turn the level off and on
and then restart the calibration procedure from Step 2
.
2 Press and hold the HOLD and ALT ZERO buttons simultaneously until SUP is displayed; this usually
takes three seconds. Release the buttons once SUP is displayed. SUP will display for a few seconds
and then the [ 0 ] is displayed. The level is now ready to be calibrated.
Each time you position the level during the calibration process, wait a minimum
of 10 seconds before pressing the HOLD button to advance to the next step.
Also ensure that the level is placed in the same position each time it is moved.
