When computing oxygen consumption or CO2 production without 'scrubbing' water vapor from the analyzed gas (as described here), a channel containing water vapor data must exist, and must be in units of kilopascals water vapor pressure. This sequence of windows allows conversion of other common units for water vapor (relative humidity, dew point, or vapor density in mass units) into kilopascals. The initial window requests the units for the water vapor channel, and whether results should be saved in a new channel:
The next window asks for the channel containing the water vapor data. If the initial units are relative humidity, a channel containing the temperature of the RH meter is also requested (or a constant temperature can be used):
- When the 'Next...' button is clicked, the calculations proceed.
