Page 197 of 202
When the Monitor is switched on, and while it is being operated, the
Monitor regularly performs a series of self-tests, which check that the
various mechanical, electrical and electronic components of the
Monitor are functioning correctly. These self-tests are described in
. You can select to disable the regular self-
tests if desired (see
). If any component is found to be
functioning outside of its specifications either a “Warning” or a
“Operating-error” message will appear on the gas monitor’s screen.
Please note: A “Warning” and/or “Operating-error” message will
only be displayed once. If the fault is still found to be present during
the next regular self-test the message will not be displayed again.
Messages are only displayed when a fault is first detected. If the fault
corrects itself and then is later found to be faulty the message will be
displayed again. It is therefore important to note the message before
pressing the INFO button, which will cause the error message to be
removed from the display.
Although the message is removed from the screen, any gas
measurements performed while the fault is still present will be
marked with an asterisk (*). By pressing INFO when such a
measurement is displayed, the Common mark “O” and/or “W”,
and in some cases, the Gas Mark “F” and Gas Mark “A” will be
shown on the display.
On the following pages, all possible “Warning” messages are listed;
all possible “Operating-errors” messages are listed; and all possible
“Interface-error” messages are listed. There is a description of each
fault as well as the possible cause(s) of each fault. The user must
evaluate the significance of each message. As long as the fault is
detected, all measurements will be marked by an asterisk. Some
“faults” are easily corrected.
