NO 3.11 4 /20mA
CO 4.25 4 /20mA
SO2 4.04 4 /20mA
O2 20.02 4 /20 mA
• Analog output
For each gas component to be measured, the current value of
the output current in mA is shown (the unit is not shown for
space reasons) as well as the start-of-scale value (either 0, 2
or 4 mA) and the full-scale value (20 mA) of the output cur‐
rent range. For information on setting the start-of-scale val‐
ues, see section Conguration: Inputs/outputs/pump: Analog
outputs (Page 137).

• Reference/bridge
– Reference: The reference voltage for the electronics of
the analyzer.
– Bridge: The supply voltage to the measuring bridge.

Power (VAC): 101 %
Raw voltage: 30.0 V
• Power/IR source
– Power: Data on the supply voltage in % of the nominal
value of the respective supply voltage (e.g.: 100% corre‐
sponds to 230 V or 120 V).
– Raw voltage: This is the raw voltage after rectication of
the transformer voltage
