GX-6000 Operator’s Manual Calibrating the 10.0 eV/Benzene PID Sensor • 248
14 . If the calibration passes, the screen will indicate PASS and will return
you to the TUBE CAL Menu.
If the reading cannot be adjusted to match the cylinder concentration, see
“Troubleshooting” on page 104.
15 . Use the SHIFT ▼ (PANIC) button to place the cursor next to ESCAPE,
then press and release the POWER/ENTER button. You will be
prompted to remove the filter tube and tube holder.

Calibration Mode Menu.
18 . Use the SHIFT ▼ (PANIC) button to place the cursor next to the
NORMAL MODE menu option, then press and release the POWER/

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
TUBE CAL
