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.
