Leakage current: ≤ 500 μA

Signal ID and Details

DATA (Do 11...Do 68): BCD output data in 6 digits

Do 1x = LSD ... Do 6x = 6th LSD

POL: BCD Polarity

ON = (–), OFF = (+)

OVF: BCD Overflow/underflow

Output given at overflow or underflow

DAV: Data Valid

ON = valid, OFF = invalid

RUN: Run

Means the meter is functioning.

ON = Measuring or testing mode

OFF = Error except overflow/underflow

No DAV or DATA output is given when

RUN signal is not provided.
