LOW HECK
Low flows indicate blockage somewhere in the pneumatic pathway.
To check the Sample flow with the external flow meter:
1. Disconnect the sample inlet tubing from the rear panel SAMPLE port.
2. Attach the outlet port of a suitable flow meter to the rear panel SAMPLE port.
•
3. The sample flow measured with the external flow meter should be within ± 10%
of the analyzer's Flow specification (Table 1-1).
•
To check the Ozone flow with the external flow meter:
1. Open the analyzer to gain access to the reaction cell.
2. Disconnect the tube going to the reaction cell's 4 mil fitting.
3. Connect the flow meter to the reaction cell's 4 mil fitting.
4. The ozone flow measured with the external flow meter should be 80 cc/min.

LOW ALIBRATION
To calibrate the Sample flow (Flow Cal) or the O
1. In the Utilities>Diagnostics>Flow Cal or Ozone Flow Cal menu (Figure 5-13), edit
the Actual Flow value by inputting the reading from the external flow meter
obtained in the corresponding check of the flow to be calibrated.
2. Press the Calibrate button.

Ensure that the inlet to the flow meter is at atmospheric pressure.
If a combined sample/ozone air dryer is installed (optional equipment), the
flow will be an additional 80 cc/min for the ozone generator supply air and 60
cc/min for the purge flow).
