Calibration

A vibration calibrator capable of generating a reference vibration of 10 mm/s RMS at 159.2 Hz (e.
g. PCE-VC20 or PCE-VC21) is required for the calibration of the vibration meter. The calibration
can be started via the sub menu Calibration. A code is required to enter this menu in order to
prevent an inadvertent overwrite of the current calibration. The required code is 1402.
The first screen shows the hint regarding the required reference vibration and the sensor of the
vibration meter needs to be mounted on the vibration calibrator.
Fig. 9 Hint for required reference vibration
After turning on the vibration calibrator and -if required- setting the reference vibration, the
calibration can be continued with the OK key. This opens the calibration screen. This screen
shows the required characteristics of the reference vibration at the top, followed by the current
measurement value of the device in green font and in the unit mm/s. It is not necessary to adjust
the device measurement parameters specifically for the calibration as only the RMS value of the
vibration velocity is evaluated for the calibration.

ATTENTION: Verify that the required reference vibration is generated by the vibration
calibrator before the calibration is performed!
