System Calibration Certificate for Accelerometer & Signal Conditioner
How to Turn Off the Displayed Calibration Date
For version 5.0.3 and later of PVC firmware:
Metrix models HI-903 and HI-913 portable vibration calibrators display the date on which the calibrator
was last calibrated at Metrix during start-up. Users who have calibrated their calibrators by following the
procedures described in this manual may wish to turn off the displayed date and affix their own proof of
calibration (typically a calibration sticker).
Contact Metrix to obtain access to the HI-903 and HI-913 portable vibration calibrator’s “secret menu”.
From here, the displayed calibration date can be turned off.
Note, earlier versions of models HI-903 and HI-913 firmware do not offer this capability. Units must be
returned to Metrix for firmware upgrade or to a local, capable representative.
