Command #181: Write Cal Signal Enable
This command writes command number to the Ultima X Gas Monitor to
enable or disable the Cal signal output. Without the Cal Signal enabled,
the 4-20 mA output will follow the gas reading during calibration. With
the Cal Signal enabled, the 4-20 mA output will be set to 3.75 ma during
calibration and be held there for one minute after calibration has ended
to allow the sensor to re-stabilize. Status group 3 indicates the current
setting of this mode.
