circuit due to permeating, conduc-
tive medium
– Exchange the instrument or send it
in for repair
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
E017 Adjustment span
too small
Carry out a fresh adjustment and in-
