20.6. Eventlog
Up to 100 events are saved in an eventlog. The *-sign indicates appearance, the #-sign disappear-
ance. Besides the event messages, this also lists power interrupts, calibrations, and similar operations,
with date and time.
This helps to interpret events – for example a deviation of the measured value shortly after a power in-
terrupt may simply be due to the unfinished polarization of the measurement.
The eventlog provides information on frequency and duration of events. You can see what events have
occurred in the past, and how long they lasted. The appearance and disappearance times allow to
check what other events had happened at that time, for example the start-up of a dosing pump, fre-
quency inverter, etc.
Note
You can save the eventlog by saving the diagnosis file.
20.7. Event help
As an addition, the instrument provides help for all events: information on possible causes, and
suggestions for possible remedies. These can be found in the menu SYSTEM=>EVENT, or – with
touch screen instruments – by touching the event message on the desktop.
We advise to follow the suggestions in the order in which they are presented.
Event message
Cause
Suggested remedies
Check measuring
input
The measuring input receives no
proper signal
Check sensor plug, check
cable, check sensor
This message appears if the measuring circuit is interrupted.
Note:
With conductivity measurements, in case of an overload of the measuring
input, 32767 might be displayed instead of the usual error message. Such
message indicates an overload of the measuring input. Take the sensor out of
the process water to check if the problem might be caused by a stray current.
If the message remains, a short-circuit is the most probable explanation,
either within the cable or in the sensor. If the message disappears when you
disconnect the sensor from the cable, the short-circuit is located in the sensor.
