g-meter Calibration

The g-meter and g-meter+ must be calibrated at least every 12 months. The calibration expiry date is shown on the underside of the instrument, on its printouts, and when using the g-meter PC program. The instrument display will also flash cd when calibration is due. The g-meter must not be used for statutory testing when the cd warning is displayed.

Only Turnkey-approved laboratories should be used to calibrate g-meters. Only our approved laboratories have the correct equipment and training to calibrate the g-meter correctly and reset the cd warning.
