Wet Process Pressure
This menu option allows you to define your wet process pressure. It also allows
you to define whether your process is operating under a positive or negative pres -
sure. Setting this value corrects wet oxygen measurements for the defined pressure.
1. Select Wet Process Press from the Setup key menu.
2. Select Positive Pressure or Negative Pressure.
You are then prompted to enter your system process pressure:
Pressure = xx.x PSIG
New Value?
3. Enter your process pressure (up to one decimal point is allowed - for example,
1.5 PSIG), then press the Enter key. If you select a positive pressure, a plus sign
(+) will appear before your value. If you select a negative pressure, a negative
sign (-) will appear before your value.
The process pressure you entered will now appear on the third display line.
4. If the correct pressure has been entered into the system, press the Enter key
without entering a new value to exit this menu option. If the pressure was incor-
rectly entered, you can reenter it at this point.
