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.
18.1. Useful accessories for trouble-shooting
PH-T: Our pH/mV simulator makes testing instruments and sensors easy,
since you can use it to test sensors, check cables, and test instrument
functions. On the next pages you will find detailed information on when and
how to use the PH-T.
Short-circuit wire: With pH meters, a simple wire bridge allows a simple test of
the measuring input. If you short-circuit the terminals of the measuring input,
the instrument will show 0mV or approx. pH 7, respectively. Attention: The pH
value depends on the current calibration values! If you had last calibrated with
an internal buffer of pH 2, for example, the displayed value will be approx. pH
2 instead of pH 7. However, the mV value will always be 0mV (+/-3mV).
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.
Spare cable: Cables are frequently causing trouble
– damaged contacts or
insulations lead to malfunctions very similar to those caused by sensor
