3.3 Normal Operation
In normal operation, the display continuously shows the current sensor reading, which will normally appear as
“0”. Once every minute, the LED display will flash the sensor’s units of measure and the gas type (i.e.”%
LEL”). If the sensor is actively experiencing any diagnostic faults, a “Fault Detected” message will scroll
across the display on the display once every minute instead of the units of measure and the gas type. At any
time, while the sensor is in “Fault Detected” mode, PGM1 or PGM2 can be swiped to prompt the sensor to
display a list of the active faults.
In normal operation, the 4-20mA current output linearly corresponds with the full-scale range.
