6.1 - SIGNALLING
Error Signalling:
Check and if necessary
re-programme the
parameters function.
Internal memory error
EEPr
Check the correct
connection of the probe
with the instrument and
check the probe works
correctly
The probe may be
interrupted or in short
circuit, or may measure
a value outside the
range allowed

Action
Reason
Error
In probe error status, the output OUT behaves as set by the
parameters “tonE” and “toFE”.
