Note All channels are user definable. If any customization has been made
to the analog output configuration, the default selections may not apply.
In the dual range mode, there are two independent analog outputs. These
are labeled simply as the "High Range" and the "Low Range". Each
channel has its own analog output range, averaging time, and span
coefficient.
This enables the sample concentration reading to be sent to the analog
outputs at two different ranges. For example, the low NO analog output
