Use Smart Ω to measure the resistance of a thermocouple sensor
It is useful to measure the resistance of a thermocouple temperature sensor. The
thermovoltage is proportional to the temperature and the impact of the resistance
measurement. Using the Smart Ω function will help you achieve precise readings
regardless of the temperature.
Use Smart Ω to measure leakage current
Use the Smart Ω function to measure leakage current or reverse current for
junction diodes. Such leakage currents are negligible and are usually measured in
units of μA or nA. Instead of having to source a high-precision multimeter with a
1 nA or 0.1 nA accuracy or a precision shunt, you can measure the leakage current
using the Smart Ω function with just a resistor from 100 kΩ to 300 kΩ.
