Sample Flow
Indicates the gas flow through the sample port of the instrument.
The value should be around 0.50 slpm. If there is an error with the
sample flow, it will read 0.00 slpm.

Lamp Current
The UV lamp current.
Conc Voltage (RAW)
Voltage from the sensor proportional to the detected signal from
the optical cell. This voltage represents the actual measurement of
gas.
Conc Voltage
Displays the detector voltage after PGA scaling.
Ref. Voltage
A voltage offset from the detector that is removed to measure the
concentration voltage. This is set to 3 V (using the input pot) at
start-up and automatically adjusts if the reference voltage drops
below 2 V or above 4 V.
Flow Voltage
[Internal Pump Option]
The current voltage measured from the sample flow.
O3 Gen. Current
[IZS Option]
Ozone generator current.
+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.
