Connecting Calibration Gas to the EGM-5
During calibration, the signal from the O
2
sensor is referenced against a gas of known O
2
concentration.
For greater accuracy, reference gas mixtures should be accurate to at least +/- 1% and traceable to NIST
standards.
Follow these instructions to calibrate the EGM-5 O2 sensor:
1. To avoid excess pressure in the sample cell and damage to the analyzer, you must place a T-fitting
between the reference gas source and the GAS IN port on the EGM-5. One end of the T-fitting should
be left open in order to relieve excess pressure, as follows:
