Calibration
Wind currents may cause false readings and poor
calibrations.
Diagnostics Protection
The detector tests the ambient air (auto zero) and the test
gas that is applied (auto span) to ensure it meets expected
values.
If an unexpected level of target gas is present during an auto
zero, the auto zero will fail for that sensor. The detector
advises which sensor(s) failed the auto zero before
proceeding to the auto span.
In auto span, if any target gas is not present or does not
meet expected values, the display will advise you of that
failure. The sensor(s) that failed to span will retain its
previous set value and not continue with the calibration
process.

The calibration cap and hose, which is shipped with the
detector, simplifies sensor testing and calibration. Figure 3
and Table 10 show how to use it when applying gas to the
sensors.
