Analog Ranges

Each analyzer has four fully configurable 4 to 20 mA analog output channels. Channel 2,
3, and 4 outputs have one sensitivity range and Channel 1 output has both high and low
ranges. The upper and lower range limits on all outputs can be adjusted for the desired
resolution. Refer to Page 4-2: Analog Flags for information on configuring the analog
outputs to track system values such as moisture concentration, flow rate, and pressure.
The output range on channel 1 can be toggled between low and high manually or au-
tomatically. The auto-range function switches channel 1 from low to high range when
the signal is close to the upper limit of the low range (~97%). Auto-range also switches
channel 1 from high to low range when the signal reaches ~85% of the upper limit
of the low range. Refer to Page 4-4: Flags1 for information on enabling/disabling the
auto-range function.
