Addendum: Calibration with Pump Module
It is highly recommended that all calibrations be done with the pump module in operation. This requires special
cylinder adapters called Flow Demand Regulators. They are available from ENMET Corp. under part number:
ƒ 03510-001 for 17 liter cylinders
ƒ 03510-002 for 34 liter cylinders.
The calibration procedures are the same as for standard ambient monitoring devices.

Addendum: Calibration of Ozone
Ozone sensors have cross sensitivity to some other gasses such as chlorine and NO2. The sensitivity of the ozone
sensor is much greater than these other gasses. If calibration gas levels of gasses such as Chlorine and NO2 are
applied while the ozone sensor is installed it will cause sever over reaction on the ozone sensor. If an ozone sensor is
to be calibrated it should be removed during all other sensor calibrations. The ozone sensor should be reinstalled and
then calibrated only after all other sensors have been calibrated.
The above factors should also be considered when monitoring relatively high concentration of other gases
For accurate detection of O3, channels with installed NO2 or Cl2 smart blocks, should be disabled. See section 1.6.1.
