l Contents of display
The following table lists the contents of the display:
Display Item Description
Type Displays one of the following detector types: TCD, FID, FID-CONV (FID
with a meta-converter), FPD, or “none”.
Input Signal Displays a value obtained by averaging the detector’s analog signal
sampled every 20 msec. that is then A/D converted, using a value that is set
to the sampling rate.
Post-filtering Signal Displays the value obtained by filtering out an input signal using the value
that has been set to the filter constant of the detector signal settings.
Standard Signal
Deviation
Indicates the standard deviation of the past 20 input signals.
Applied Voltage Value Indicates TCD bridge voltage (TCD only).
Current Value Indicates TCD bridge current (TCD only).
Flame detection level Displays the setpoint for the flame detection level. (FID, FID-CONV, FPD)
Thermocouple Signal Displays a thermocouple signal. (FID, FID-CONV, FPD)
Flame Detection Status Displays the flame detection status (burning/burning stopped). (FID, FID-
CONV, FPD)
Converter Voltage Value Displays a converter voltage value. (FID-CONV only)
5.2.4 Temperature Control Unit Operation Window
The Temperature Control Unit Operation window displays the statuses of temperature controllers
at every section of the analyzer. Display information differs depending on the GC1000 type.
The updating cycle for data other than isothermal oven temperature (for GC1000S/E/E) or
programmed temperature oven temperature (GC1000D/T/W) is 1 second.
Moreover, this window allows you to change the ON/OFF statuses of the temperature controller
at each section.
