5.7.2.2 Analyzer Status: Diagnostic Values: O
2
Diagnostic Values
This dialog displays the diagnostic values of the optional oxygen
sensor.
S Sensorsig is the current pessure-compensated voltage of the O
2
sensor in mV
S O
2
is the current oxygen value (negative values are also possible)
S Date is the installation date of the O
2
sensor (see Section 5.8.2)
S Inst.volt is the pressure-compensated voltage of the O
2
sensor
when it was installed.
5.7.2.3 Analyzer Status: Diagnostic Values: Pressure Sensor Diagnosis
This dialog displays the diagnostic values of the pressure sensor (see
Section 5.8.3). The displayed values have the following meaning:
S ADU pressure is the voltage of the pressure sensor measured at
the output of the A/D converter.
S Pressure air is the current atmospheric pressure in mbar.
5.7.2.4 Analyzer Status: Diagnostic Values: Other Diagnostic Values
This menu is used to call further diagnostic functions. You can call the
following dialogs:
S Power/IR source
Power: Data on the mains voltage in % of the nominal value of the
respective mains voltage (e.g.: 100 % corresponds to 230 V or
120 V).
Raw voltage: Raw voltage following the rectification
Source 1, Source 2: Data on the IR source voltage(s), in Volt
provided the IR source is present.
S Reference/Bridge
Reference: The reference voltage for the electronics of the
analyzer.
Bridge: The supply voltage to the measuring bridge.
S LCD temperature
The temperature which determines the display contrast. Refer to
Section 5.9.4.2 for adjustment of the LCD contrast.
