POL: BCD Polarity

ON = (–), OFF = (+)

OVF: BCD Overflow/underflow (scaling error)

Output given at overflow or underflow (scaling error)

DAV: Data Valid

ON = valid, OFF = invalid

RUN: Run

Means the meter is functioning.

OFF = Error except the scaling error

No DAV or DATA output is given when

RUN signal is not provided.
