3.5.3 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 10% to 50% of selected full-scale 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).
3.5.4 Set Range
Set Range is used to change full-scale ranges. This is selectable between 0-20, 0-50, 0-100ppm, and 0-200ppm.
The current range can be viewed in View Sensor Status using instruction given in Section 3.5.2 View Sensor
Status.
The menu item appears as: “Set Range”.
From the “Set Range” text scroll, hold the programming 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 Range”). The display will then switch to “XXX“ (where XXX is the current Range). Swipe the magnet
momentarily over PGM2 to increase or PGM1 to decrease the range Level until the desired range is displayed.
Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value. The display will scroll “Range
Saved”, and revert to “Set Range” text scroll.
