Errors F1, F2, F3, F5 or F6
for longer than 8 hours,
recognition of attempts to
manipulate. No further
measurements are carried
out.

Measure dependent on error code.
Error message F8 must be reset by
service department.

Fault in the electronics

Exchange the meter

Note:

Reset the message F8 in the parameterization mode manual-

ly or with the service software. All other error messages are deleted
automatically once the error has been rectified.
