1. From the Gas Settings menu, highlight Gas Type .
2. Press the MODIFY soft key until the desired value displays.
3. Press the BACK soft key to return to the Settings menu.
Gas Temperature
This setting is the temperature of the gas flowing through the high- or low-flow port. The
Analyzer uses this information to improve the accuracy of the flow measurements. All
temperatures are in °C.
To enter a gas temperature:
1. From the
Gas Settings menu, highlight Gas Temperature .
2. Press the MODIFY soft key to display the value field.
3. Input the desired value from the keypad.
Note
The Analyzer accepts temperatures between 0 and 99 °C. No decimal
values or fractions are allowed.
4. Press the ENTER soft key to save the change or the ESCAPE soft key to cancel the
change.
5. Press the BACK soft key to return to the Settings menu.
Ambient Temperature
This setting is the room temperature air flowing through the high-or low-flow ports.
To change ambient temperature:
1. From the
Gas Settings menu, highlight Ambient Temp .
2. Press the MODIFY soft key to display the value field.
3. Input the desired value from the keypad.
Note
The Analyzer accepts temperatures between 0 and 99 °C. No decimal
values or fractions are allowed.
4. Press the ENTER soft key to save the change or the ESCAPE soft key to cancel the
change.
5. Press the BACK soft key to return to the Settings menu.
Relative Humidity
This setting is the relative humidity in the air flowing through the high- and low-flow
ports and is used only for STPD and BTPS corrections. The relative humidity is not used
in calculating the effective viscosity on the Analyzer; however, the gas calculator in the
VT Plus PC software does use relative humidity in determining the effective viscosity of
user-defined gases.
To change relative humidity:
1. From the
Gas Settings menu, highlight Rel. Humidity .
2. Press the MODIFY soft key to display the value field.
