Calibration
6.1
General
The device can be calibrated either manually using this procedure or automatically
using the GALAXY Test Stand. Refer to 9.1 of the appendix.
Calibration must be performed using a flow regulator with a flow rate set to
0.25 litres per minute.
If a battery charging cycle is interrupted before it is completed [4 hours for a fully
discharged battery], allow the instrument’s internal temperature to stabilise for
30 minutes before performing a Calibration.
Under normal circumstances MSA recommends calibration at least
every six months, however, many European countries have their own
guidelines. Please check your national legislation.

The Fresh Air Setup has limits. The zero of any sensor that is outside of these limits
will not be adjusted by the FAS command.
Warning!
Do not activate the Fresh Air Setup unless you are certain you are in
fresh, uncontaminated air; otherwise, inaccurate readings can occur
which can falsely indicate that a hazardous atmosphere is safe. If you
have any doubts as to the quality of the surrounding air, do not use the
Fresh Air Setup feature. Do not use the Fresh Air Setup as a substitute
for daily calibration checks. The calibration check is required to verify
span accuracy. Failure to follow this warning can result in serious personal injury or death.
