Calibration and Adjustment by the User

The GM70 can be calibrated and fine control adjustment can be carried

out by the user. Note that this adjustment does not correspond to the

accurate factory adjustment. The user adjustment is recommended only if

the reading error is less than 10% of the measuring range in the low-end

and less than 20% of the measuring range in the high-end. The

calibration report supplied with the product is not valid after the

adjustment.

CAUTION

You cannot revert to factory settings after the user adjustment!

Adjustment is carried out

- by using reference gases and a field check adapter,

- by comparing two probes: the one to be adjusted and the other a

calibrated probe.

NOTE

Adjustment cannot be done with the GM70PUMP.

To open the adjustment mode you need to press the adjustment button

(Figure 16 below) located in the probe handle. The GMH70 handle does

not meet the IP65 classification requirements after removal of the screw

that covers the adjustment button.
