9.11 Defining the test criteria for the calibration check
You can perform a control measurement to check the precision of a selected calibra-
tion. The check is based on the measurement uncertainty (tolerance) specified for
the calibration standard (calibration foil) used during the control measurement. To
be able to check a calibration, you have to enter for this calibration the measurement
uncertainty or tolerance for the calibration standard you want to use for the check
(control measurement).
Before you start
You know the tolerance or the measurement uncertainty (k=2) for the calibra-
tion standard to be used later during the control measurement. These values
can be noted in a certificate or on the calibration standard itself.
The probe is connected to the gauge containing the calibration whose test cri-
teria you want to define.
Please also refer to section "Important to know", 68.
If the calibration whose test parameters you want to enter for the check is
locked, you need to know the lock code.
To define the test criteria
1. Select the calibration for which you want to enter the test criteria: > Calibra-
tions > OK > select name of calibration > OK.
2. Prompted to set the lock code?
• Yes: Set the lock code and deactivate the lock function, 73.
Function is deactivated:
• No: Continue with step 3.
3. Open the settings menu: Define Cal. Check > OK.
4. Select the format in which you have the uncertainty/tolerance values for the
calibration standard you intend to use for the check (control measurement)
later: select desired tolerance value > OK.
Parameter is activated:
Parameter selection:
• No: Check function deactivated
• Abs. Tol., example: ± 1.5 μm
