+
"E:Conductivity" The fluid conductivity is
out of range.
The message is
displayed if the
monitoring of the fluid
conductivity has been
activated, depending on
the set thresholds ERR
LO and ERR HI (see
chpt. 9.13.2).
→ Go into the "Sensor"
function of the
Diagnostic menu to
read the measured
fluid temperature
(chpt. 9.13.2).
→ If necessary, clean and/

"E:Polarization" The polarisation slope is
too high.
The message is

has been activated,
depending on the set
threshold ERR HI (see
