Calibration
Before you start
 The test parameters for the selected calibration are defined.
Defining the test settings, 68.
 The probe is connected to the gauge containing the calibration you want to
check.
 In the gauge is the batch open to which the calibration is assigned, you want to
check.
 Reference piece and a calibration standard already used for the calibration pro-
cedure are ready. You can find the parts you need on the calibration info page:
> Calibrations > OK > select name of calibration > OK > Info.
 Before the control measurement is carried out, the gauge with connected probe
must have been switched on for at least 10 minutes! This is necessary to en-
sure that all gauge components have reached their operating temperature.
Otherwise, slightly increased measurement errors can occur!
 If the calibration you want to check is locked, you need to know the lock code.
To check the desired calibration
1. Select the calibration whose measurement accuracy you want to check: >
Calibrations > OK > select name of calibration > OK.
2. Prompted to set the lock code?
- Yes: Set the lock code and deactivate the lock function, 70.
Function is deactivated:
- No: Continue with step 3.
3. Start the function: Check Calibration > OK.
4. Take a few control measurements on the calibration standard. We recommend
taking 10 measurements.
Description of the displayed variables on the Check Calibration page:
- Val.: Nominal value of the calibration standard, set in the Def. Cal. Check
menu.
- Δabs: Tolerance/uncertainty of the calibration standard, set in the Def. Cal.
Check menu.
- Nmin: Minimum number of required measurements
