2. SAFETY WARNING
This analyser extracts combustion gases that may be toxic in relatively
low concentrations. These gases are exhausted from the back of the
instrument.
This analyser 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 atmosphere 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).
