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 with the sub menu Calibration. 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 the vibration calibrator was turned on, the calibration can be continued with the OK button.
This leads to the calibration screen. This screen again shows the characteristics of the required
reference vibration at the top, followed by the current measurement value of the device in a green
font with 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 during
this procedure.

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