WARNINGS
SAFETY NOTES
Before using this meter, read all safety information carefully .
“WARNING” is used to indicate conditions or actions that may pose physical hazards to the user .
“CAUTION” is used to indicate conditions or actions that may damage this instrument .
WARNING!
This analyzer extracts combustion gases that may be toxic in relatively low concentrations . These gases are exhausted from
the back of the instrument .
This analyzer must only be used in well-ventilated locations by trained and
competent persons after due consideration of all the potential hazards.
Users of portable gas detectors are recommended to conduct a “bump” check before relying on the unit to verify an atmo-
sphere is free from hazard . A “bump” test is a means of verifying that an instrument is working within acceptable limits by
briefly exposing to a known gas mixture formulated to change the output of all the sensors present . (This is different from a
calibration where the instrument is also exposed to a known gas mixture but is allowed to settle to a steady figure and the
reading adjusted to the stated gas concentration of the test gas) .
BATTERIES
BATTERY TYPE
This analyzer has been designed for use with disposable alkaline batteries or rechargeable Nickel Metal Hydride (NiMH) batteries . No other battery
types are recommended .
WARNING!
The battery charger unit must only be used when NiMH batteries are fitted. Do not mix NiMH cells of different
capacities or from different manufacturers. All four cells must be identical
REPLACING BATTERIES
Turn over the analyzer, remove its protective rubber cover and fit 4 “AA” batteries in the battery compartment .
Take great care to ensure
they are fitted with the correct battery polarity.
Replace the battery cover and protective rubber cover .
Note: When changing the batteries on the instrument the memory will store the date and time for up to one
minute, if outside this time it may be necessary to re-enter the details.
Date and time may also need to be reset if re-chargeable batteries are allowed to totally discharge.
Switch the analyzer on and check that the analyzer’s time and date are correct . To reset see
USING THE MENU, Section 5
.
CHARGING NIMH BATTERIES
Ensure that you use the correct charger . The part number is AACA4 .
To fully charge NiMH batteries:
The charger must be connected and switched on .
When charging, the red Battery Charging Indicator will illuminate .
After a few seconds, the display will show “CHARGING BATTERY” if they need extra charge . If they are already fully charged this message
will not appear .
The first charge should be for 12 hours continuously . NiMH batteries are suitable for top up charging at any time, even for short periods .
BATTERY DISPOSAL
Always dispose of depleted batteries using approved disposal methods that protect the environment .
