How to avoid thermal EMF errors

In this episode of ‘Making Good Measurements’ we show what happens when using various types of lead and their coating, and the thermal electromotive force errors that occur when mixing different metals together.

Effect of Test Lead Resistance on Measurement Error

In this video we cover the problems that occur when trying to measure high resistance with the wrong test leads. This video also includes how to measure the test leads being used.

Noise and Electrical Measurements

In this video we demonstrate the effects of noise on electrical measurements, and how to overcome the most common sources of noise.
