Default Span
The software will set the SPAN adjustment based on the average output of the oxygen at a specific oxygen
concentration. For example, with factory default settings, when a span gas is introduced, the micro-processor will
display oxygen reading 50% of the span gas value, indicating that the sensor output is within the specified
limits. This feature allows the user to check the sensor’s signal output without removing it from the sensor housing.
