Analyser error messages
For a list of standard error codes and for more
information, please refer to section ‘8.0 Problem
Solving’ of the operating manual.
Analyser warnings
There are two types of warning messages
displayed; general warnings that may not
necessarily affect the instrument’s function, for
example battery power low, and operational
parameters that could affect the performance of
the analyser, for example CO
2
out of calibration.
Analyser Data Manager
Analyser Data Manager software enables the
operator to maximise the operation of the
instrument. Instrument readings and event log
data can be downloaded to a PC for further
analysis.
Area mode
‘Area’ is the soft-key used to begin operating in
area or room monitoring mode. This mode
automatically stores a rolling average N
2
O
reading every 15 minutes. G200 only.
Backlight
LED illumination of the LCD display, turns off
after 30 seconds, pressing any key relights the
display.
Battery charge
A full battery charge will take approximately
three hours.
Calibration
The process that an instrument will undergo to
enable it to measure and display the various
parameters in accordance with the
manufacturer’s specification.
Chemical cell
Type of gas detector which can be fitted
internally to the analyser at the time of
manufacture.
Clean air purge
Process used to clear out gas from the inlet pipe
and the analyser’s gas sensors prior to taking a
new reading.
CO
Carbon monoxide gas.
CO
2
Carbon dioxide gas.
Contrast adjustment
Adjustable setting which darkens or lightens the
text displayed on the screen. Typically, this is
used to compensate for different environmental
temperatures. High temperature causes the
display to darken and low temperature causes
the display to lighten.
Data logging
A mode of operation that enables the user to
leave the analyser unattended to take readings
automatically at predetermined times. The
