Over range codes
Over range codes are errors above the maximum
allowed reading and will be displayed with more
than chevrons (>>.>)
ppm
Parts per million
Predetermined
Pressure
Set up prior to use via Analyser Data Manager
software.
Maximum input pressure 300mb maximum flow
250ml.
Pump
The device used to transfer a gas sample into the
instrument where that sample is not under
pressure. Select the ‘Pump’ key on the analyser
to activate.
Regulator flow
The regulator’s flow is factory set. It only
requires a few turns to open, no adjustment is
available.
Sample tube
Tube used to transfer sample gas from the
source to the analyser.
Span
The point at which the gas analyser is calibrated
when a known concentration of the target gas is
present.
Temperature probe
External device to enable the instrument to
display data and record the temperature
readings. This is an optional feature.
Under range codes
Under range codes are errors below zero and will
be displayed with less than chevrons (<<.<)
User calibration
Users have the facility to calibrate the analyser
between services. User calibration of the gas
analyser will improve the data accuracy in the
range of the calibration gases used.
Verify
Checking instruments operation using calibration
gas.
Warm-up self test
Predetermined self-test sequence to test the
analyser functions which takes place after the
analyser is switched on and lasts approximately
30-40 seconds.
Warranty
The instrument is guaranteed against defect in
materials and workmanship for a period of 12
months from the date of shipment to the user
and is subject to the recommended service and
recalibration requirements.
Zero
The point at which the gas analyser is calibrated
when there is none of the target gas present.
