Programmable Read Only Memory) and the integrity of the data
stored in the Monitor’s Working Memory (RAM).
Hardware test
This test checks that the electrical, mechanical and electronic
parts of the Monitor are functioning properly.
The following parts of the Monitor are checked: the pump; the
valves in the pneumatic system; the infra-red light source; the
power supply; the filter carousel; the motor which drives the
chopper wheel; the external vibration level (to make sure that it
does not contribute to the signal measured in the analysis cell);
the analogue circuitry and the microphones (to check that they
are functioning properly).
If you do not wish the Monitor to perform the hardware test
during a partial reset, you can disable it (see section 5.4.3 ). This
also disables the regular self-tests.
If any part of the Monitor is found to be functioning incorrectly a
message will appear in the display to inform the user of the problem.
For example:
The user must acknowledge receipt of such a message by pressing
INFO. Operating errors and warning messages are listed in table-
form in Chapter 15 at the end of this manual.
If a fault is found in any of the blocks of data stored in the Working
Memory, the Monitor will automatically set the parameters in the
relevant compartment(s) to their default values, and the Monitor will
send the following message on its display screen:
WARNING: MEMORY SET TO DEFAULT
ERROR DETECTED IN XXXXX MEMORY
Where XXXXX denotes the part of the memory that has been
affected. When such a message is received users must check the
contents of the relevant memory to find out which data has been
affected before continuing to operate the Monitor.
