Calibration
7 Calibration
For a correct measurement, the gage must be adjusted to the extreme values
of zero and "maximum height" (= air value). This is done by means of a cali-
bration. The extreme and height values are recorded using a glass plate and
one or two calibration shims in order to compensate the influences for future
measurements.
Please observe the following information
Perform the calibration carefully! This is the benchmark for the accuracy
to which the following measurements can be performed. - Measurements
can never be more accurate than the calibration!
7.1 Calibration - When necessary?
•
After switching on the gage
•
To start a series of measurements
7.2 Performing a calibration
Handle the calibration shims (foils) with care. Replace soiled, bent,
scratched or cracked calibration shims.
Required materials
•
Glass plate 605-306 from scope of supply
•
1 or 2 calibration shims from scope of supply, depending on the mea-
surement accuracy required
Before you start
•
The gage is switched on
•
Glass plate and calibration shim ready for use. The parts you need de-
pends on the measurement accuracy required.
