• 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 Configuration: 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.
This menu is used to call further diagnostic functions. You can
call the following values:
• Unlimited concentration values
Measured values that are not limited by the large measuring
range are displayed here. Negative measured values can also
be output here.
• 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 rectification of
the transformer voltage
