Instruction Manual

TO CORRECT: Reduce the “CNT BY” count by value to 001. If you have an active decimal point selected, move
the decimal point one or more positions to the right.
UOM.OVF
POSSIBLE CAUSE: Selection of unit of measure displayed (“RDG.6=0”) moves the display reading
one place to the left causing a numerical overflow.
TO CORRECT: If you have an active decimal point, move he decimal point position one or more positions to the
right.
SERIAL
POSSIBLE CAUSE: A configuring change has been attempted via the front panel buttons while the serial
communications port is actively communicating with the meter.
TO CORRECT: Either lockout the front panel buttons by removing the jumpers S3A & S3C or disconnect the serial
communications option.
