6. IF SOMETHING GOES WRONG

PROBLEM
No display
No external temperature reading
Conductivity fails to stabilize in all
solutions measured
No variation of conductivity
The instrument displays SOS-ALARM
Displays 1999
Conductimeter C 320
Check the 230 V supply.
Check the connection of the power supply unit to
the power connector
Check the connection of the temperature probe
Check the value of the probe
(107 Ω at 20 °C)
Check that the conductivity cell is correctly
immersed.
Check the connection of the cell.
Check the condition.
If necessary, replace it, or perform tests with pure
resistances.
For 1kΩ the value displayed 1000 µS.
You are over the range limit.
Switch to the next higher range.
