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:

● Types of calibration: Zero point, span gas, normalization, and phase 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.

Validation

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.
