The low calibration gas must be a high quality certified mixture (usually nitrogen N6.0)
containing trace Oxygen. Mixtures between 1000 ppm to 4000 ppm are preferred.
*
If, during a calibration or validation routine, the measurement is outside the specified range,
a status message is displayed to indicate that there may be a problem (for example, the
wrong calibration gas has been introduced, or the transducer has drifted excessively). The
status can be over-ridden but the history will still remain.
**
Range and background gas as per analyser specification. For optimal performance use
either low or high calibration point to be a single component gas.
