Regular Check Of The Measuring Means - KARL DEUTSCH LEPTOSKOP 2042 Instruction Manual

13.2 Regular check of the measuring means

Measuring means like the instrument with accompanying calibrating stan-
dards are subject to tear and wear so the measuring accuracy may be af-
fected.
It is for this reason that the measuring means should be subjected suffi-
ciently often to a regular check in order to verify the faultless function and
adequate accuracy.
The check can be executed by means of a reference coating, e.g. ...
a calibration foil on the test block Fe or NFe or
a permanent coating of known thickness on known substrate (e.g. coating
sample)
Use the menu items Calibration -> Default Cal -> Default Cal ok to recall
the default calibration of the LEPTOSKOP 2042.
Measure the reference coating
If the permissible measurement inaccuracy is exceeded (see Technical Data,
section 18) it is recommended to execute an instrument check at KARL
DEUTSCH's in order to re-calibrate the LEPTOSKOP 2042.
