Pre-calibration

If needed, a pre-calibration of your GRAS equipment can be performed. This is useful when the user wants to document the equipment´s performance before service or repair of the unit.

The pre-calibration data is valuable when the user suspects that there might be something wrong with the equipment which has already been used for measurements. Finally, this data can be used for making post-measurement corrections of the results. After service or repair of the unit, a traceable or accredited calibration must be made.
