Diagnostics Protection:
The detector test the ambient air (auto zero) and the test gas
applied (auto span) to ensure it meets expected values.
In auto zero if any background target gas is present, the
sensor(s) affected will read no and exit the auto zero function
retaining the previous set value(s).
In auto span if any target gas is not present or does not meet
expected values the sensor(s) will advise you and exit
calibration mode retaining the previous set value(s).
Applying Gas to the Sensors
The calibration hose, which is shipped with the detector,
simplifies sensor testing and calibration. Table 10 and
Figure 3 show how to use it when applying gas to the
sensors.
