I need to change the Oxygen and Helium cells in my ATA Pro, how do I do this?
The very simple process of sensor replacement is outlined in the video below
- Following a sensor change you should carry out a helium zero and span to match the helium cell to your device
- If your device is reporting incorrect values of helium it may be necessary to carry out a helium calibration
The video below demonstrates helium cell replacement and full calibration.
Please note: Prior to setting the helium span value, the device should be exposed to a span gas for a minimum of 2 minutes.
