7.4 Calibration of Instrument

The instrument-integrated functions concerning avoidance of zero-

drift are described in chapter 5.3 of this instruction manual.

The possibility for re-calibration of the Gas Monitor 

2240 PROcheck

 is 

conventionally included in the scope of functions of every software 
version. For reference see separate calibration instructions for service 
personal.
The re-calibration job may be done by authorized service personnel only.
Naturally the re-calibration may also be performed by the manufacturer, 
with a manufacturer's calibration certificate.

Inform yourself which type of re-calibration is being required by

your competent local authority.
