D.1.9 Resistance (CALYS 100)
Range Resolution
400 Ω 1 mΩ
4000 Ω 10 mΩ
Temperature coefficient: < (6 ppm R + 1 ppm Range)/°C from -10°C to +18°C and from +28°C to +50 °C.
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.
