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.
