Diagnostic Screen Overview
The Diagnostic Screen contains sensor data and status information useful for trouble shooting various fault
conditions. An explanation of the information provided on each line of this screen is listed below, including
normal operating ranges.
DET: Detector Voltage – Peak-to-peak output of the IR sensor. In the absence of gas, this value
range is 3.900V to 4.500V.
AVE: Average Detector Voltage – Running average of the values displayed in line 1.
ZERO: Zero Voltage – IR sensor output that was stored during the last purge cycle and has the
same range as line 1.
