IR Source
The drive voltage of the IR source 5 V ± 0.5 V.
Conc. Voltage (RAW)
Voltage from the sensor proportional to the detected signal
from the measurement cell. This voltage represents the actual
measurement of gas.
Conc. Voltage
Displays the detector voltage after PGA scaling.
Ref. Voltage
The reference voltage is a measure of the IR source intensity.
Flow Voltage
[Internal Pump Option]
The current voltage measured from the flow block PCA.
Cooler Voltage
Voltage of the peltier cooler within the IR detector (~1.25 V).
Opto. Strength
The measurement of the signal strength coming from the opto-
detector on the correlation wheel.
+5V Supply
+5 V power supply.
+12V Supply
+12 V power supply.
+Analog Supply
+12 V (primary) power supply. The value should be within ± 2 V.
-Analog Supply
-12 V (primary) power supply. The value should be within ± 2 V.
