Do not use excessive force on the battery cover fixing screws.
Make sure the rubber seal is correctly in place.
If you replace the batteries in the field, you can, of course, recharge them later
when you return to base.
If the instrument is to be stored for more than four weeks, ensure that the batteries
are fully charged. After four weeks, charge the batteries again.
However, if the instrument does not operate after prolonged storage, the batteries
have become discharged and will be unable to ‘fast charge’. They will, therefore,
need a longer charge time.
Factory calibration
The instrument is not supplied with a calibration certificate. The instrument is
supplied with a functional check sheet.
It is recommended that the instrument be returned to Gas Data Limited once every
five years for a general inspection.
