Calibration

There are two kinds of calibrations procedures:

 Calibration (red field calibration unit)
 Verification (black reference calibration unit).

Please refer to the manual for an explanation of these two procedures and when to perform them.

During daily use only a quick calibration has to be done. There is no need with LTL-X Mark II to make a Zero
calibration as was the case with the predecessor LTL-X. The apparatus will guide you through the procedure.

Calibration procedure

Before a calibration make sure that the calibration unit and front window are clean.

Calibration using the red field calibration unit:

 Mount the calibration unit underneath at the front of the instrument with the white ceramic on the

calibration unit facing the tower of the instrument. It is important that the pins on the side of the unit
fit into the slots in the LTL-X Mark II structure.

Press the button and then the OK button. Check and if necessary correct the calibration value
shown in the display so it matches the value written on label on the calibration unit. Press the OK
button to start the calibration.

The calibration procedure is now done. Remove the calibration unit and store it properly. Press to return to
the measurement display.
