Calibrating the SCC-TC0X Using a Thermocouple 
Calibrator

To calibrate the system using a thermocouple calibrator, complete the 
following steps:

1.

Make sure that the thermocouple connections at both the SCC and the 
thermocouple calibrator are at the same temperature.

2.

Connect the thermocouple calibrator to the SCC-TC0X. For best 
results, use thermocouple wire of the same length and type that you 
use in the thermocouple.

3.

Set the thermocouple calibrator to the required calibration 
temperature.

4.

Measure the calibrator voltage using the SCC-TC0X.

5.

Convert the measured calibrator voltage to a temperature measurement 
as described in the Converting Voltage Measurements to Temperature 
Measurements section.

6.

Adjust the potentiometer on the top of the SCC-TC0X so that the 
measured temperature is equal to the calibration temperature.

NI-DAQ includes thermocouple and thermistor conversion utilities that implement 

the conversions required in steps 3 and 5 of the following procedure. Refer to your 
software documentation for more information on these utilities.

Your software environment may return only voltage measurements from 
E Series DAQ devices. If so, you must convert voltage measurements to 
temperature measurements. To make this conversion, complete the 
following steps:

1.

Measure the thermocouple voltage.

a.

Read the thermocouple channel on the E Series DAQ device 
V

 [CH(X)].

b.

Calculate the thermocouple voltage by using the following 
formula:
