The detector saves the calibration and returns to normal operation.
Auto Span

Span sensors in the following order:
•
Exotics (NH

)
•
Single gas

)
•
PID
Note
A generator must be used for O
3
and ClO
2
sensors.
To ensure accurate calibration, a single gas calibration cap
must be used to calibrate O
3
and ClO
2
sensors.

:
Use a Tedlar bag as a buffer between the generator
and the detector (using the single gas calibration cap) to
regulate the flow rate to ensure accurate readings.
Allow the Tedlar bag to fill for several minutes before
initiating calibration.
•
O
3
:
Calibrate using the generator and the single gas
calibration cap. Do not use a Tedlar bag.
Set the generator to 0.5 ppm at a flow rate of 0.5 l/min.
Depending upon the gas cylinder being used, one or all four sensors
can be calibrated at one time.
