Calibrating the distance measurement

Manual Calibration

In the menu navigate to :

OPTIONS > SETTINGS > SENSORS > DISTANCE

and adjust the factor by small changes using the + and - menu entries. After each change take a length measurement of a line with a known length and compare the result. If the measurement is too short increase the factor otherwise decrease it.

Automatic Calibration

Put in place a line with markers separated by 5m precisely if the unit is set to METER, or 15 ft if set to IMPERIAL.
Select OPTIONS > SETTINGS > SENSORS > DISTANCE > AUTO
Take a measure between those two markers as if they were two stations(tie-offs) in a cave.
The Standard survey process is explained here
Once done you’ll get a message Adjustment : X , X being the adjustment factor ( How much the factor needs to be changed to have a good measure).
Repeat that operation until you get an adjustment factor of 0 or 1.
