Appendix 4 RTD Calibration Wiring Examples

RTD calibration wiring examples are shown below.
Three-wire System
Wiring Example
2560A
Make the resistances of the three lead wires the same.
Red, white, A, and B are defined in IEC 60751: 2008 and JIS C 1604: 2013.
Configuring the 2560A
Set the RTD, temperature, and the like, and calibrate.
For details on 2560A configuration, see sections 6.1 to 6.4.
Four-wire System
Wiring Example
2560A
Configuring the 2560A
Set the RTD, temperature, and the like, and calibrate.
For details on 2560A configuration, see sections 6.1 to 6.4.
Note
To calibrate more accurately, use the fork terminal adapter set 758921 (included or sold separately) to
connect the lead wires (A and B) on the sensing side to the fastening sections of the 2560A output terminals.
