Appendix 2 Thermocouple Calibration Wiring
Examples
Thermocouple calibration wiring examples are shown below.
When Using 0°C Reference Junction
Wiring Example
Thermometer, data
logger, and the like that
support thermocouple
input
2553A
Thermocouple wires
or compensating
lead wires
Copper wires
0°C reference junction
(ice bath, 0°C reference temperature device, etc.)
Configuring the 2553A
1.
Set the reference junction compensation mode to manual input (MAN) and the reference
junction temperature to 0.00°C.
For details on the configuration procedure, see section 6.5.
2.
Set the thermocouple type, temperature, and the like, and calibrate.
For details on the configuration procedure, see sections 6.1 to 6.3.
When Using the Internal Reference Junction Compensation
Wiring Example
Thermometer, data
logger, and the like that
support thermocouple
input
2553A
Thermocouple wires
or compensating lead wires
Configuring the 2553A
1.
Set the reference junction compensation mode to internal (INT).
For details on the configuration procedure, see section 6.5.
2.
Set the thermocouple type, temperature, and the like, and calibrate.
• For details on the configuration procedure, see sections 6.1 to 6.3.
• Reference junction compensation error is added to the thermocouple temperature source accuracy.
