6 . Reconnect the tubing to the open end of the dehumidifier filter to help preserve its
life. If the filter begins to appear wet, it needs to be replaced.
Calibrating the 11.7 eV PID Sensor
Setting the Fresh Air Reading
See “Setting the Fresh Air Reading” on page 71 for instructions to set the fresh air
reading.
Performing an AUTO CAL
See “Calibrating Using the Auto Calibration Method” on page 71 for instructions to
perform an automatic calibration while keeping the following in mind:
•
If the 11.7 eV PID sensor is one of two PID sensors installed in your instrument, both
channels may 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.
•
When turning off the GX-6000 after performing a calibration, follow the instructions
in “Turning Off a GX-6000 with an 11.7 eV PID Sensor” on page 235.
