Question

Sketch the calibration hook-up needed to calibrate the following type T thermocouple transmitter.

- Thermocouple transmitter with range of -26 to +86°C
- Ambient temperature of 22°C
- Equipment available:
- 24 V power supply
- Fluke 744

Transmitter input millivolts
Transmitter output milliamps

Answer 1

To calibrate a type T thermocouple transmitter, you need to connect it to a power supply, measure the input millivolts using a Fluke 744, and adjust the output milliamps to match the desired temperature range.

Step-by-step explanation:

To calibrate a type T thermocouple transmitter with a range of -26 to +86°C, you will need the following calibration hook-up:

• Connect the - terminal of the thermocouple transmitter to the negative terminal of the power supply.
• Connect the + terminal of the thermocouple transmitter to the positive terminal of the power supply.
• Measure the input millivolts of the transmitter using the Fluke 744.
• Adjust the output milliamps of the transmitter to match the desired temperature range using the Fluke 744.
