7. Error codes
The meter continuously runs a self-diagnosis and can thus
recognise and display various installation or meter errors:
Error code Error
FL nEG Incorrect flow direction
if necessary in exchange with:
DIFF nEG Negative temperature difference
if necessary in exchange with:
F0 No flow can be measured
F1 Interruption in the hot side temper-
ature sensor
F2 Interruption in cold side tempera-
ture sensor
F3 Electronics for temperature evalua-
tion defective
F4 Battery flat
F5 Short-circuit hot side temperature
sensor
F6 Short-circuit cold side temperature
sensor
F7 Error in the internal memory
holding
F8 Errors F1, F2, F3, F5 or F6 for
longer than 8 hours, recognition of
attempts to manipulate.
No further measurements are
carried out.
F9 Error in the electronics
