228 • Appendix H: 10.0 eV/Benzene PID Sensor
GX-6000 Operator’s Manual
Entering a CAL CODE
NOTE:
A PID-003L 10.0 eV/benzene sensor must be installed in order for the CAL
CODE 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 enter the new calibration code before using the new filter tubes.
An alternative to performing a TUBE CAL using a benzene calibration cylinder is to enter
the calibration code found on the filter tube box. The cal code adjusts the instrument’s
reading in Benzene Select Mode to account for the effect that the filter tube has on the PID
sensor’s response to benzene. It is listed on the tube box’s label and is a letter between A
and J.
If you go through the CAL CODE procedure, there is no need to perform a TUBE CAL
using a benzene calibration cylinder.
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).
