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).
3.5.2 Set AutoSpan Level
Set AutoSpan Level is used to set the span gas concentration level that is being used to calibrate the sensor.
This level is adjustable from 5% to 95% of range (100% LEL range or CO2) or 2% to 50% (50% LEL range).
The current setting can be viewed in View Program Status.
The menu item appears as: “Set AutoSpan Level”.
From the Set AutoSpan Level text scroll, hold the magnet over PGM1 or PGM2 until the “” prompt appears
and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts to scroll “Set
Level”). The display will switch to “XX“(where XX is the current gas level). Swipe the magnet momentarily
over PGM2 to increase or PGM1 to decrease the AutoSpan Level until the correct level is displayed. When
the correct level is achieved, hold the magnet over PGM1 or PGM2 for 3-4 seconds to accept the new value.
The display will scroll “Level Saved”, and revert to “Set AutoSpan Level” text scroll.
Move to another menu item by executing a momentary hold, or return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Set AutoSpan Level” 4 times and then return to Normal
Operation).
