The menu item appears as: “
Set Gas Factor
”.
From the
Set Gas Factor
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 Factor”).
The display will then switch to “X.XX“ (where X.XX is the current gas factor). Swipe the magnet momentarily
over PGM2 to increase or PGM1 to decrease the gas factor level until the correct value is displayed. Hold the
magnet over PGM1 or PGM2 for 3 seconds to accept the new value. The display will scroll “Factor Saved”,
and revert to “Set Gas Factor” 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 Gas Factor” 4 times and then return to Normal
Operation).
3.5.5
Set Cal Factor
Because of the catalytic bead sensor’s almost universal response to combustible gases, the FP-700 sensor can be
span calibrated with any of the combustible gases listed in Table 2 above. This specific gas is referred to as the
“cal gas”.
NOTE:
The default value for cal factor is 1.0. This would be used when methane is the cal gas.
Values other than 1.0 would be used when the span cal gas is not methane.
