Troubleshooting
17-4
“I OVSC”
POSSIBLE CAUSE: The input scale and/or offset values chosen are large
enough to drive the display into numerical overflow.
TO CORRECT:
Reduce the input and/or the input scaling/offset. Refer
to “IN.SC.OF” in Section 9.2.5.
“R OVSC”
POSSIBLE CAUSE: The reading scale and/or offset values chosen are
large enough to drive the display into numerical over-
flow.
TO CORRECT:
Reduce the reading scale/offset and/or move the
active decimal point to the right. Reducing input
scale/offset is not required, because the input
overscale message has higher priority than this
message and would be displayed if there were an
input overscale.
“CB OVF”
POSSIBLE CAUSE: CNT BY (count by value) has been changed causing
the display to round up to a numerical overflow.
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 the 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.
