Setting alarm levels
We recommend that alarm levels are set to user specifications as soon as possible before being used for the
first time. Please see page 19 for details of how to set alarm levels.
Setting date and time
We recommend that the correct local date and time be set to the instrument as soon as possible before
being used for the first time. Please see page 23 for details on how to set the date and time.
Selecting a gas from the inte rnal gas table
P instruments leave Ion Science pre-set for gas type TVOC (total volatile organic compounds).
Instruments are factory calibrated against isobutylene and all response factors are equivalent to this. By
changing the gas from the gas table all readings will be given using that gases response factor. To change
the selected gas please see pages 23 & 24.
Rechargeable Batteries
Although P instruments leave the factory fully charged, prolonged periods of storage may result in
the battery pack discharging. We recommend charging the instrument for 12 hours before use. See the
battery section of this manual page 38.
Alkaline Batteries
Fit the battery pack supplied with the P. For more information please see the battery section of
