The detector should be allowed to stabilize for 1 minute,
after activation, prior to calibration or a bump test.
Diagnostics Protection
The detector tests 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
Err 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 display 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.
