2. Peaks are not output or are extremely small; FID used as detector.
Cause Countermeasure
The hydrogen flame is out.
If the igniter filament is red hot even though the ignition
operation is not being executed, this means that the
hydrogen flame is out. Ignite the hydrogen flame.
The nozzle is clogged.
Clean (using, for example, CLEANING WIRE,
201-79229-01) or replace the nozzle. (Refer to 4.11.2
Maintenance/Inspection
in the instruction manual for
details on mounting and removing the nozzle.)
A high voltage is not output.
Set the detector to ON and check the voltage between
the end of the nozzle (+) and earth (−).
If a DC voltage of approx. 160 V (when measured using
a tester with an impedance of 10 M
Ω
) is not output, it
means that there is a fault in the high-voltage circuit or
contact failure or disconnection in the high-voltage
electrode assembly.
Replace the FID control board or repair or replace the
high-voltage electrode assembly.
3. Peaks are not output or are extremely small; FPD used as detector.
Cause Countermeasure
The flow rate for hydrogen or air is inappropriate.
Check the actual measurement value of the flow rate for
hydrogen or air and also check the piping to the
detector.
4. Peaks are not output or are extremely small; FTD used as detector.
Cause Countermeasure
Hydrogen is not flowing into the detector.
Check the actual measurement value of the flow rate for
hydrogen or air and also check the piping to the
detector.
The FTD collector has reached the end of its
service life.
Replace the FTD collector.
7.5 Other Problems
1. The display is dark or goes out.
Cause Countermeasure
Backlight ON/OFF or contrast has been adjusted
inappropriately.
Readjust backlight ON/OFF and contrast.
The value set for automatic OFF operation of the
backlight in "Other configuration settings
" is
inappropriate.
Change the value set for automatic OFF operation of the
backlight.
2. Chromatopac is not started by GCSTART when the Chromatopac signal cable is
used.
Cause Countermeasure
The channel started by the link device code in
"Configuration settings
" is not ON.
Set the channel started to ON.
