“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 16.4.
“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 re quired,
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 nu mer i cal 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.
“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 disconnect the serial cable, or press ‘MENU’ for configuration
of the meter.
