When the status list sequence is complete, the ITM will revert to the “View Sensor Status” text scroll. The
user can either: 1) review list again by executing another 3-4 second hold, 2) move to another menu item by
executing a momentary hold over PGM1 or PGM2, or 3) return to Normal Operation via automatic timeout of
about 15 seconds (the display will scroll “View Sensor Status” 4 times and then return to Normal Operation).

This level is adjustable from 1% to 99% of range depending on the range of the sensor (see Table 2) . The
