g-meter Calibration

The g-meter and g-meter+ must be calibrated at least every 24 months, and preferably 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.
