A Partial Reset of the Monitor
When the Monitor performs a partial reset a number of self-tests
are automatically performed. The types of tests performed depend
only upon the time, which has elapsed since the Monitor was last
switched on.
·
If more than 10 min. have elapsed since the Monitor was
switched on it will perform the software, data-integrity, and
hardware tests when switched on again.
·
If less than 10 min. have elapsed since the Monitor was switched
on it will perform only the data-integrity tests when switched on
again.
There are essentially 3 types of self-tests which can be performed
during a “partial reset” – a software test, a data-integrity test and
a hardware test.
It takes the Monitor only a few seconds to perform the data-
integrity tests; and about 3 minutes to perform both the software
and hardware test. The different tests are explained below.
Software test
This test checks the information in the Monitor’s software (ROM –
Read Only Memory.)
Data-integrity test
This test checks the integrity of the data stored in the Monitor’s
Source Memory (i.e. its EEPROM – Electrically Erasable
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
). 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.
