If the measuring hardware of the 2830 is not ready or the internal communication is broken, then
this alarm messages will be displayed.
Shut down the system and restart it.
2831 not connected
This alarm message will be displayed when no communication between the 2830 and 2831 over
Ethernet is possible.
Check the Ethernet cable on the rear panel of both units.
AC Current Trip
If the AC measuring current during a C Tan
δ measurement exceed 5 mA then the HV and the
heater will be switched off, an actual running sequence will be aborted and this alarm messages
will be displayed.
Check the test cell for flashover, short-circuits and minimal impedance. To detect a flashover, apply
a low voltage and increase the voltage in small steps until the flashover occurs.
The alarm message can be quitted by clicking on it.
DC current Trip
If the DC measuring current during a DC Resistivity measurement exceed 3 mA then the HV and
the heater will be switched off, an actual running sequence will be aborted and this alarm messages
will be displayed.
Check the test cell for flashover, short-circuits and minimal impedance. To detect a flashover, apply
a low voltage and increase the voltage in small steps until the flashover occurs.
The alarm message can be quitted by clicking on it.
Old 2967 Heater Cable is plugged in
When a control cable of the old Tettex 2967 heater controller is used to connect the solid test cell
2914 with the 2831 then this alarm message will be displayed.
Use controller cable which is delivered with the 2830/2831 system.
Solid Control cable switched
When the control cable of the solid test cell 2914 is connected reversely this alarm message will
be displayed.
Disconnect the control cable and connect it reversely.
Temp/Reg Cables switched
Because of safety issues an alarm message will be displayed, and the heater switched off if the
liquid test cell temperature is 25 °C hotter than the heater temperature. It is supposed that the Temp
