None
NDIR only; Signal gain setting at manufacturing time.
Historical values of SIGNAL-GAIN. This show how the instrument was working when
it was tested during the manufacturing process. This value is loaded automatically by
the manufacturing data storage function.
SIGNAL_GAIN
Output
None
2-element floating point array except FID, 3-elements
Both elements between 0 and 5000.
mA
Heater Current (NDIR, FID), Block heater current (CLD)
Fan Current (NDIR, FID), Converter heater current (CLD)
Air FET Current (FID)
Shows the current through the control FET for these devices. Used as a diagnostic
tool.
Output
None
NDIR, PMD, HFID: 2-element floating point array; FU): single floating point; CLD:
3-element floating point.
Both elements between 0 and 100
None
Fan FET duty cycle (NDIR, PMD), Temperature controller duty cycle (FID, HFID), Fan
duty cycle (CLD).
Heater FET duty cycle (NDIR, PMD), Oven controller duty cycle (HFID), Converter
duty cycle (CLD).
Detector cooler (Peltier) duty cycle (CLD).
Shows the duty cycle of the control algorithm for these devices.
