Calibration Procedure Using 'Cc/Sec' Units - ION GasCheck G Instrument User Manual

Avoid bending the inner probe as this will affect the GasCheck G's accuracy.
GasCheck G can detect changes in Humidity and Carbon dioxide, therefore avoid
breathing on the probe.
Avoid pressurizing the sample bag as this will cause significant errors in reading.

Calibration procedure using 'cc/sec' units

Please read this entire procedure before proceeding with this calibration routine.
GasCheck G can detect changes in Humidity and Carbon dioxide, therefore avoid
breathing on the probe.
After each custom calibration, a bump test should be carried out afterwards to check the
response.
Great care should be taken to ensure the calibration gas is neither pressurised or restricts
flow to the instruments probe. Changes in flow of gas to the sensor will result in
significant errors in readings.
Unrivaled Gas Detection.
1. Follow the instructions of the CalCheck unit, the pointer of the pressure gauge
must be resting over the green segment.
2. Select the 'Custom Cal' symbol from the instruments menu.
3. Ensure the instrument is in clean air and then press the ENTER key, the instrument
will Zero, this will take a few seconds but once complete a 'Ready' message will
appear.
4. Insert the instruments probe into the CalChecks outlet and press the ENTER key.
The instrument will automatically sequence through the cold and hot stages of
calibration but when finished gives a summary of values.
5. Pressing the ENTER key will return back to the calibration option screen. Press the
ESC key to start using the instrument or press the ENTER key to recalibrate again.
