CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the measures listed above, the
instrument must be taken out of operation immediately.

Causes
One of the measuring inputs has a
very high measured value
With a measuring input with a
small voltage signal, this is only
connected on one side or the
input is open
Not all activated interpolation
points are parameterised
The arithmetic result gives an
overrange

Error in the configuration memory
With a division, the measured
value of the divisor is very small
