Group D Display Cause Remedial action
D1 LINE INT. Power failure
Note: no counting during power
failure Delete error message in
RESET/QUIT. menu, reset
totalizer if necessary.
D2 OVERFL. I Current output range exceeded Check instrument parameters
and correct if necessary. Reset
totalizer. Error message is
deleted automatically after
cause has been eliminated.
D3 OVERFL. P Pulse output range exceeded
Note:
totalizer deviation is possible Check instrument parameters
and correct if necessary. Reset
totalizer. Error message is
deleted automatically after
cause has been eliminated.
D4 ADW A/D converter range exceeded Error message is deleted
automatically after cause has
been eliminated.
D5 FATAL.ERROR Fatal error, all outputs are set to
