Appendix 3 Thermocouple Calibration Wiring
Thermocouple calibration wiring examples are shown below.
When Using 0°C Reference Junction
Wiring Example
2560A
Configuring the 2560A
1.
Set the reference junction compensation mode to manual input (MAN) and the reference
junction temperature to 0.00°C.
For details on 2560A configuration, see section 6.6.
2. Set the thermocouple type, temperature, and the like, and calibrate.
For details on 2560A configuration, see sections 6.1 to 6.4.
When Using the Internal Reference Junction Compensation
Wiring Example
2560A
Thermocouple wires or compensating lead wires
Configuring the 2560A
1. Set the reference junction compensation mode to internal (INT).
For details on 2560A configuration, see section 6.6.
2.
Set the thermocouple type, temperature, and the like, and calibrate.
• For details on 2560A configuration, see sections 6.1 to 6.4.
• Reference junction compensation error is added to the thermocouple temperature source accuracy.
