6.2.8 Error messages (F4-)
I f the 8 bars beneath the digits start flashing, an error has occurred in the measuring transmitter/current
output. Since the pointer indication is independent from the electric measuring transmitter, it may show the
correct measuring value even if the transmitter is defective. Function F41 allows checking of assigned error
codes.
Error codes are called onto the display as follows:
