sensing elements can vary. Calibrate with a known
reference gas before each monitoring session and every few hours when in use
(recommendation is within two hours).
To calibrate the sensor
1. Attach the reference gas cylinder to the calibration unit.
2. Connect one end of the nylon hose to the pipe stub on the calibration unit and
the other end to the pipe stub on the pod’s calibration chamber.
3. Connect the sensor cable to the pod.
4. Remove the sensor cap and insert the membraned sensor into the pod’s
calibration chamber.
5. Swing the chamber cover down to secure the sensor.
CAUTION: To prevent leakage, always use two batteries of the same type and
expiration date to power the calibration unit.
NOTE: Always use the recommended gas tubing. Using different tubing will cause
inaccurate measurements.
