Calibration
This does not apply for duct mount applications or if the process adapter number
is used (see installation instructions for PIR 7x00 accessories).
3. Make sure that the sealing surfaces around the openings of the splash guard
are clean. The insect guard does not have to be removed.
4. Connect the tubing to the barbed fitting.
5. Enter the menu, see 8.6.3 Entering the menu
9.3 Gas flow for calibrations
Gas flow varies depending on the sensor.
Gas flow should correspond to the environmental conditions during operation (e. g.
duct measurement with higher flows than 2 l/min)
9.4 Calibration setup with test gas cylinder
Fig. 15 Calibration setup with test gas cylinder
9.5 Zero calibration
Ambient air can be used to zero the sensor instead of Nitrogen or Synthetic Air only
if the area is known to be free of the target gas or any gas to which the sensor may
be cross-sensitive (as listed on the sensor data sheet). In this case, no cylinder or
calibration adapter is needed for the zero calibration.
EC sensor 0.5 l/min ± 10%
All other sensors 0.5 l/min - 2 l/min
