8.1.2.4 Analyzer status: Diagnostics values: (Paramagnetic) O2 sensor
Sensorsig: 1339 mV
O2 : 20.77 %
This dialog displays the diagnostics values of the paramagnetic
oxygen sensor (option). Meaning:
• Sensorsig is the current voltage of the O
2
sensor in mV
• O
2
is the current oxygen value. Negative values are also pos‐
sible here
8.1.2.5 Analyzer status: Diagnostics values: H2S sensor
Sensorsig.: 884 nA
H2S : 0.78 vpm
Inst.Date:30.11.2012
Inst.Curr.: 500 nA
This dialog displays the diagnostics values of the optional H
2
S
sensor. Meaning:
• Sensorsig. is the actual current of the H
2
S sensor in nA
• H
2
S is the current H
2
S measured value in vpm. Negative val‐
ues are also possible here.
• Inst. date is the installation date of the H
2
S sensor (see sec‐
tion Calibration: H2S sensor: Dening the installation
(Page 121))
• Inst. cur is the pressure-compensated current per vpm H
2
S of
the sensor when it was installed.
8.1.2.6 Diagnostics: Diagnostic values: Pressure and temperature
Pressure sens. diagn
Temperature of IR
Temperature of LCD
Temperature of UV
8123
This dialog shows various diagnostic values for pressure
and temperature.
The parameters for the IR measurement and UV measure‐
ment are shown in the adjacent screen. Depending on the
device version, one of these two options might be omitted.
You can select between the following parameters:
Pressure ADC:1.778 V
Pressure amb. air:
1011 mbar
81231
• Pressure sensor
This dialog displays the diagnostic values of the pres‐
sure sensor (see section Calibration: Pressure sensor
(Page 124)). The displayed values have the following
meaning:
– ADC pressure is the actual voltage of the pressure
sensor measured at the output of the A/D converter.
– Air pressure is the actual atmospheric pressure in
mbar.
81232
Temperature of IR
chamber: 41.1 °C
• IR sample chamber
The temperature of the rst IR detector is shown here.
