5. CHECKING THE PROPER OPERATION
There is a built-in Self test and Service menu in the analyzer.
5.1. Self test
5.1.1. Self test Screens
Self test can be used to check the operation of
the instrument.
The first panel shows general information about
the instrument. (See menu on the left.)
With the new COMB card, the PCPNIF firmware
version is empty, and the MPU firmware version
holds the COMB version number.
The second and third panel contains tested
parameters, as follow:
HGB light (LED is on).
Measuring Electrode voltage, current and
offset.
Amplifier Noise test during a 5-second period.
Amplifier transfer by generating 20000 test
pulses, incl. gain related peak value, noise
related deviation.
Atmospheric pressure stands for outer
pressure.
Vacuum reports pump operation (vacuum made
by the pump in a 10-second period of time).
Drift represents pressure loss of vacuum
measured in a 10-second period of time.
Power ±12V shows the amplifier voltage value.
Power Batt reports the voltage value of the
battery. If battery fails, system time will stop.
Core Temp shows CPU temperature of the
Control and Measurement Board (COMB).
Overall test result is displayed, which can be
Successful (in case of every test result is OK) or
Errors (if HIGH, LOW or ERROR).
At the end of a result line status message is displayed, which means that the actual test
result is at the normal range (OK), higher (HIGH), lower (LOW) than the pre-determined
limits, or the result is an error (ERROR).
