Cal On Foil (Calibration On Zero And Foil) - KARL DEUTSCH LEPTOSKOP 2042 Instruction Manual

12.2.2 Cal on Foil (Calibration on zero and foil)

When to use?
If the default calibration ex works is not accurate enough.
In addition to the zero calibration, if you want to execute a two point calibra-
tion (zero and foil) to achieve higher measurement accuracy (see Technical
Data).
If the substrate is the same compared with the last zero calibration, how-
ever the measuring range is changed.
How to proceed after initiation of menu topic "Cal on Foil":
The instrument will change to measurement operation in order to acquire
calibration values for the zero calibration. Execute the zero calibration as
described in section 12.2.1. Confirm the zero calibration via
Put calibration foil onto the uncoated substrate.
Place probe on the foil (thickness of foil = nominal value). Execute some
measurements in order to minimize the placing inaccuracies. A current
measured value can be deleted with ESC.

Press if you want to confirm the foil measurements. In each case the
last measured value can be deleted with
Subsequently a request on the nominal value of the used foil is shown. In-
put as described under section 7.2.1.
After confirmation by striking
operation based on the calibration executed for "Cal on Foil".
