5.2 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.

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!
