Analyser error messages
For a list of standard error codes and for
more information, please refer to section
“Problem Solving” on page 8-1 of the oper-
ating 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 opera-
tional parameters that could affect the per-
formance of the analyser, for example CO
2
out of calibration.
Battery charge
A full battery charge will take approxi-
mately three hours.
Calibration
The process that an instrument will undergo
to enable it to measure and display the vari-
ous parameters in accordance with the man-
ufacturer’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
2
Carbon dioxide gas.
Contrast adjustment
Adjustable setting which darkens or light-
ens the text displayed on the screen. Typi-
cally, 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 reading interval and pump
run-time may be adjusted prior to com-
mencing the logging cycle.
