Check wiring (short circuit, interruption?)
E.002
Temperature sensor defective, temperature
reading too high
E.005
Conductivity electrode defective, measured
value too low.
Check conductivity electrode and, if necessary, replace
it. Check electrical connection.
E.006
Conductivity electrode defective, measured
value too high.
