Troubleshooting and Maintenance
Correcting for Different
Background Gases
(cont.)
When the oxygen cell is used in a background gas other than nitrogen,
users must enter the gas’s current multiplier, listed in Table 2-7. The
Series 1 will apply the appropriate correction to the oxygen signal.
The original calibration values for nitrogen are programmed into the
“Oxygen Probe Calibration” section. However, the meter uses the
current multiplier to determine the correct oxygen concentration.
