Multiple Inlet Sampling
When two or more pump inlets are assigned and turned on, EXO samples from each inlet one at a time in a repeating sequence.
For each inlet, EXO:
Performs a two-minute purge to clear the previous sample.
Draws air from one inlet at a time and updates gas readings for the duration of the configured sample time.
After the sample time ends, EXO purges again before switching to the next inlet.
Gas readings are paused during each purge, resulting in a gap between samples from different inlets.
