7 . Remove the CO
2
scrubber from the VOC zero filter. Be sure the VOC
zero filter’s tubing stays on the VOC zero filter.
8 . Reattach the CO
2
scrubber’s tubing to the open end of the scrubber.
9 . Remove the VOC zero filter from the GX-6000’s inlet fitting.
10 . Reinstall the plugs on each end of the VOC zero filter.
NOTE: Do not store the CO
2
scrubber and VOC zero filter connected
together. They must be separated and appropriately plugged for
storage.
IR Calibration
1 . See “Calibrating Using the Auto Calibration Method” on page 71 or
“Calibrating Using the Single Calibration Method” on page 84 for
instructions to perform a calibration.
NOTE: If you are using the IR HC or IR CH
4
sensors in their autoranging
configuration, be sure to calibrate the range you’d like the most
accuracy in (either %LEL or %vol).
NOTE: If there is a PID sensor installed in your instrument and you are
calibrating an IR CH
4
sensor with %vol concentrations, either
calibrate the PID sensor first or allow enough time for the %vol CH
4
gas to flush out before calibrating the PID sensor.
IR Bump Testing
1 . See “Performing a Bump Test” on page 90 for instructions to perform a
bump test.
