3.3 Normal Operation
In normal operation, the ITM Display continuously shows the current sensor reading, which will normally
appear as “ 0 ”. Once every 60 seconds the LED display will flash the sensor’s measurement units and gas
type (i.e. ppm VOC). If the sensor is actively experiencing any diagnostic faults, a “Fault Detected” message
will scroll across the display on the ITM 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 linearity corresponds with the full-scale range. The RS-485
Modbus™ serial output provides the current gas reading and complete fault status on a continuous basis when
polled by the master device.
