varies according to how far the oxygen concentration in the sample
is from the gas in contact with the sensor at start up (usually air).
Figs 4 & 5 show the typical response time from an air condition for
N and L type sensors. Once the sensor is purged down, it
responds in a few seconds to large changes of oxygen
concentration within the instrument's span. Short time excursions to
high levels of oxygen, such as may be experienced during
calibration, are recovered from in a matter of a few minutes.
4.4 Sensor failure detection
All types of sensor used on the G1010 fail to a low output or
concentration reading.
