Calibration

Connect hoses. Integrate flowmeter with hose distributor.

Using a test gas ampoule

Test gas ampoules are only used for the sensitivity adjustment for the target gas.

Equipment:
– calibration flask (order no. 68 03 407) 
– adapter (order no. 68 04 620)
– Test gas ampoule
– hose, type appropriate to the gas properties (e.g. FKM hose order 

no. 12 07 068)

1. Plug the adapter onto the calibration flask.
2. Connect hoses.

6.3 

Adjusting the zero-point

Prerequisite:
– The warm-up phase of the sensor is completed (see section 5.5).
– Test gas supply is prepared (see section 6.2).

 Zero adjustment can be aborted at any time. To abort during calibration, select

If no entries are made, the gas detector automatically switches over to measuring 
mode after 15 minutes.
