20. Trouble-Shooting
In case of an event, the Neon
®
instrument provides a variety of functions to assist you:
˃
Event messages on the display, declaring the nature of the event.
˃
An event help containing suggestions how to solve the problem.
˃
An event log that stores up to 100 event messages
˃
An info menu, showing all settings and current values
˃
A reset function to restore factory settings
˃
A diagnosis file in case that you need external help. The diagnosis file will allow your contact
person to assess the situation.
20.1. Useful accessories for trouble-shooting
˃
Test resistor: With conductivity instruments you can check the measuring input by connecting a
test resistor to the terminals of the measuring input.
˃
Spare sensor: Sensors are consumables, and fragile. Exchanging a sensor can speed up trouble-
shooting: If the problem remains, it was probably not caused by the sensor. If it has vanished, the
sensor needs to be replaced or at least cleaned and regenerated.
˃
Conductivity cables: Cables are among the most common sources of trouble – torn wires or
damaged insulations lead to measuring problems similar to those caused by sensor damages.
With a second cable such problems can easily be located and eliminated.
˃
Conductivity test solutions: We recommend using commercially available ready-to-use KCl solu-
tions to avoid errors caused by dilution or contamination.
20.2. Contact
In SYSTEM=>CONTACT you can store contact data of a contact person who might help in case of
problems. With restricted access (code 0202) this data can be viewed if not altered.
Note
You can have the contact data displayed on the desktop, if you select
“contact” as desktop design in the menu SYSTEM=>DISPLAY.
20.3. Diagnosis file
In case of problems, it might be useful to provide an external contact person with an overview of the
current situation. To that purpose save the diagnosis file on your SD card. It contains all current values
and settings and the eventlog.
