4.7.1. Detector Outputs
The output levels from the detector within the receiver and within the transmitter
are displayed here. Dt is the detector level at the transmitter and Dr is the
detector level at the receiver. The level of Dr is typically between 15,000 and
25,000, and will vary according to duct width, the gain setting and the opacity in
the duct, Dt (set by the transmitter pot) is typically similar to Dr.
4.7.2. Rx Gain
The receiver gain factor is displayed here. This can be either high or low and is
set during the commissioning procedure according to the duct width.
4.7.3. Calibration Data
Kcal is the calibration gain factor calculated during the calibration routine.
Kwkg is the gain factor including any auto zero adjustment that may have taken
place.
