3.9 Calibration
The device can be calibrated either manually using this procedure or
automatically using the GALAXY Test Stand. Refer to 7.7 of the appendix.
Calibration must be performed using a flow regulator with a flow rate set to
0.25 liters 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
stabilize 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.
