Flow Calibration Procedure

5-14 | Thermox WDG-V

Calibration of the flow meter is only required if the sample flow is not vented to

atmosphere. Performing a calibration will create an offset to compensate for any

pressure effect. An accurate external flow measurement is required to perform the

calibration and is not supplied with the analyzer.

Figure 5-17. Flow Configuration Procedure.

1. From the main menu screen, press the ENTER/MENU key to access the

calibration menu.

2. Use the left and/or right navigation arrows to locate the FLOW SENSOR

CALIBRATION menu and press the ENTER/MENU key.

3. Enter the currently measured flow from an external device using the keypad

and select the appropriate units.

4. When you have completed this screen, navigate to the ACCEPT button and

press the ENTER/MENU key to continue.

5. Flow rate will now be compensated.

Flow calibration is valid only if pressure remains consistent. Any sig-



nificant change in sample pressure will require recalibration.
