Combustion analysis
In order to perform the calibration, the following tools are needed:
- Known concentration gas cylinder suitable for the sensor, complete with a pressure regulator
WARNING!
For the oxygen sensor on site calibration, the zero value calibration must be carried out with nitrogen
or any other gas mixture which DOES NOT contain oxygen.
- Flow meter.
- Hose with ' T ' shaped junction, in order to connect the cylinder to the instrument and the flow meter.
Following, the suggested stabilization times for the sensors on-site calibration.

Calibration procedure
→
1. Start the instrument
WARNING
Make sure autozero is execute in clean air and terminates correctly.
Do not connect the gas probe to the instrument.
Check the battery charge level or connect the power adapter to avoid data loss
during recalibration.
