E013
no measured val-
ue available
– Short-circuit due to bridging by con-
ductive buildup between process
fitting and electrode
– Remove buildup - if necessary,
mount a protective tube
Shortcircuit in the
probe, e.g. be-
cause of moisture
in the housing
– Remove the electronics module out
of the probe and check the resistor
between the two marked plug con-
nections according to the figure in
paragraph "
Check the resistance in
the probe
".
– There should be no contact
between any of the connections
(high resistance)
– If there is still a connection -
exchange the instrument or return
it for repair
