210 • Appendix H: 10.0 eV/Benzene PID Sensor
GX-6000 Operator’s Manual
•
The PID Gas Name Screen operates as described in “PID Gas Name Screen” on
page 48 but is factory set up for and calibrated to benzene and appears as shown
below. If there are 2 PID sensors installed in your GX-6000, the PID Gas Name
Screens will appear in Display Mode in the following order regardless of their position
in the flow system: 10.0 eV/benzene, 10.6 eV, 11.7 eV.
Measuring Mode
The 10.0 eV/benzene sensor detects VOCs in the 0-100.00 ppm range in Measuring Mode.
See “Measuring Mode, Normal Operation” on page 35 for a complete description of
Measuring Mode.
If the 10.0 eV/benzene PID sensor is one of two PID sensors installed in your instrument,
as shipped from the factory, the 10.0 eV/benzene PID channel will say “BNZ” and the low
or high range PID channel will say “VOC”.
If you change the target gas of the 10.0 ev/benzene PID sensor to something other than
benzene in Display Mode, both channels will appear as “VOC”. In that case, the channel
that appears first will be based on the following sensor priority.
NOTE:
If you have changed the factory-set channel assignments using the
CONFIGURE CH
menu item in User Mode, the order of displayed sensors
may be different and you will need to remember how you set your instrument
up.
