241 • Calibrating the 10.0 eV/Benzene PID Sensor GX-6000 Operator’s Manual
Performing a SINGLE CAL
See “Calibrating Using the Single Calibration Method” on page 84 for
instructions to perform a single calibration while keeping the following in
mind:
• 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 239).
• If the 10.0 eV/benzene PID sensor is one of two PID sensors installed in
your instrument, both channels will appear as “VOC”. The channel that
appears first will be based on the following sensor priority. Be sure to
select the correct PID sensor for calibration.
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.
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.
