These instruments are primarily for a dynamometer but I like the idea of using them else where when needed. Yes I can put the thermocouple in different locations if needed, I like to explore worst case ...

The PWM will vary from 0 to 100%, the zero and 100% I am sure is covered. I will also need to measure motor casing temperatures; however th...
