GX-6000 Operator’s Manual
Appendix H: 10.0 eV/Benzene PID Sensor • 221
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.
Performing a TUBE CAL
NOTE:
A PID-003L 10.0 eV/benzene sensor must be installed in order for the TUBE
CAL menu item to appear in Calibration Mode.
NOTE:
If you begin to use filter tubes from a new box and if the calibration code shown
on the new box is different than the calibration code shown on the old box, you
must perform a TUBE CAL operation using one of the tubes from the new box.
WARNING:
If you take the GX-6000 to an area that is 10 or 15 degrees different
than the previous area, allow the instrument 45 minutes to acclimate
before taking any readings. Failure to do so may cause the calibration
to be inaccurate.
To calibrate the 10.0 eV/benzene sensor in TUBE CAL, you will need:
•
A benzene calibration cylinder. RKI Instruments, Inc. recommends a concentration of
5 ppm.
•
A demand-flow regulator to provide adequate sample gas flow.
•
Non-absorbent tubing.
•
Tube holder and filter tube.
Be sure that you are doing a complete calibration as appropriate for your application and
for the calibration gas you have available (see “Important Calibration Information” on
page 219).
