Item Description
Type Indicates the detector type. It is either “TCD”, “FID”, “FID-MC” (FID having methane
converter), “FPD”, or “None”.
Input Signal The input signal is sampled every 20 msec, and this analog signal is converted into
digital form, averaged at the sampling rate, and displayed.
Filtered Signal The input signal is ltered using the lter constant of detector signal settings and
displayed.
Standard Deviation Indicates the standard deviation of the past 20 input signals.
Voltage Indicates the TCD bridge voltage. (TCD only)
Current Indicates the TCD bridge current. (TCD only)
Flame Level Indicates the preset Flame Detection Level. (FID, FID-MC, FPD)
Therm. Signal Displays the thermocouple signals. (FID, FID-MC, FPD)
Flame Status Indicates the Flame Detection status (Flame On or Flame Out). (FID, FID-MC, FPD)
Voltage of MC Indicates the converter voltage. (FID-MC only)
