Automatic detection of connection scheme: 2 wire, 3-wire or 4-wire.
For 2 wire connection, the measurement includes the resistance of the line.
For 3 wire connection, add the out-of-balance of the line resistances.
Open circuit terminal voltage < 10 V.
Continuity test:
Open circuit for R > 1000
Ω.
Closed circuit for R < 1000
Ω.
