Similarly, measuring the thermistor performance by converting the
ADS1248 code into resistor value based on equation 8. At the same
time, using 8 ½ voltmeter to read back the actual thermistor value.
In this way, the measured resistance and resistance error can be
measured as shown is figure 17, 18. Steinhart–Hart equation can be
used to convert the thermistor resistance into temperature. The
measured temperature and temperature error are shown in figure 19,
20. Simulating the thermocouple voltage using Keithley and it can be
read back accurately by 8 ½ voltmeter. Measured result can be got
by converting the ADS1248 digital code to voltage. Inverse
Polynomials provide the temperature from the known thermocouple
voltage (translate error by Inverse Polynomials is limited to
0.05°C which can be ignored). Figure 12, 13 show the measured
voltage and error actual from ADS1298 with voltage generated by
Keithley. Figure 14, 15 show the measured temperature and
temperature error and temperature error using Inverse Polynomials.
After calibration, the voltage error is less than +/-2.5uV and
temperature error is less than +/-0.1°C.
