8.10.2. Diagnostic Screen Overview
The Diagnostic Screen contains sensor data and status
information useful for trouble shooting various fault
conditions. An explanation of each line is given 
below along with normal operating ranges.
DET: Detector Voltage - Peak-to-peak output of the
IR sensor, in the absence of gas this value can range
from 3.900V to 4.500V.
AVE: Average Detector Voltage - Running 
average of the values displayed in line 1 (DET).
ZERO: Zero Voltage - IR sensor output that was
stored during the last purge cycle and has the same
range as line 1 (DET).
NOISE: A 16-point running average of the noise 
portion of IR bench output. This reading is valuable
mainly when refrigerant is not
present.
