Cal On Layer (Calibration On Unknown Coating) - KARL DEUTSCH LEPTOSKOP 2042 Instruction Manual

12.2.4 Cal on Layer (Calibration on unknown coating)

When to use?
Only with measurements on Fe material.
If you want to know the thickness of a layer but you aren't able to execute a
zero calibration on the uncoated reference material (e. g. if the coating
needs to remain intact and no uncoated reference substrate is available).
How to proceed after initiation of menu topic "Cal on Layer":
At first the instrument will change to the measuring display requesting the
first measurement on the unknown layer.
Execute several measurements on the unknown layer (indicated type of
calibration: "Cal-X") . Confirm the measurements by striking the key
Put a foil of known thickness onto the unknown coating of the material.
Execute several measurements on the foil (indicated type of calibration:
"Foil"). Confirm the measurements by striking the key
Enter the thickness of the used foil when the request for nominal value ap-
pears.
After confirmation by striking
operation based on the calibration executed for "Cal on Layer".
Follow-up thickness measurements refer to the distance of the layer to the
non-accessible material surface.
