5.7.2 Analyzer Status: Diagnostic Values
The diagnostic values which can be displayed provide important
information for troubleshooting and adjustments. You can select four
different function groups in this menu:
5.7.2.1 Analyzer Status: Diagnostic Values: IR Diagnostic Values
In this submenu, you can call the diagnostic values of the infrared
measuring ranges:
S
ADU are voltage and signal values of the analog-to-digital converter
prior to temperature compensation. These values are specific to the
component.
S
V-ADUt are voltage and signal values of the analog-to-digital
converter following temperature compensation. T in the bottom line
corresponds to the temperature of the analyzer section, TS the
temperature of the IR source (
not yet implemented. ”*****” = no
measured value).
S
Raw values are the measured values in % of the full-scale value
(= 100 %).
S
Not limited concen. are the values as in measuring mode except
that you can approximately display the concentrations here even
with an upward or downward violation of the largest range. Negative
values are also displayed (live zero). The current measuring range
is output on this display in the last two columns.
