Calibration/validation
Difference between calibration/validation
Calibration
In a calibration, the device is adapted to its measurement task(s). For the actual value to be
equal to the setpoint, the device changes one or more calibration factors during calibration.
Calibration parameters are assigned manually. Calibrations are distinguished by the
following features:
● Person groups
– "Customer calibrations" (zero point and/or span gas calibrations)
– "Factory calibrations" (normalization and phase calibration).
The following section only deals with "customer calibrations". Factory calibrations:"

● Single/total: Calibration of only one or all measuring ranges
● Measuring range
● Component
After the start of a calibration, a wizard in the display supports you with preset calibration
steps.
You use a validation to check whether the deviation from the last calibration is still within the
validation tolerance. If the deviation is outside the validation tolerance, a new calibration is
necessary.
Validation uses the same process steps as calibration. But the validation operation checks
whether the deviation between the actual value and setpoint is still within an assignable
tolerance band. No calibration factors are changed in the process.
If a validation detects a tolerance violation, a corresponding message is output. The
message disappears after a successful calibration.
