Operating mode
In operating mode, you can view device parameters or adjust the device and set the parameters.
This supplement only describes the functions relevant for operating the H
control functions can be found in the standard operating instructions of the ULTRAMAT 23 (C79000-G52xx-C216-03).

Maint.Req.: 373,50 nA
Fault : 74,70 nA
The H S sensor ages with increasing operating time, thereby steadily decreasing its sensitivity. It has almost reached the
2
end of its service life (maintenance requirement) when it has lots 50% of its sensitivity. The sensor must be replaced. If the
sensitivity drops below 10%, error message S30 (sensitivity of H
Diagnostic values
The displayed diagnostic values provide important information for troubleshooting and calibration tasks. To view the
diagnostic values of the H
Diagnostics -> Diagnostic values -> Probe diagnostic values -> Choose component -> H
The following screen appears:
Sensorsig.: 4886
H2S : 6.5 vpm

This dialog shows the diagnostic values of the H
● Probe current is the current pressure-corrected current of the H
● H S is the current hydrogen sulphide measured value in vpm. Negative values are also possible here.
2
● Date is the installation date of the H
● Installation current is the pressure-corrected current per vpm H
