Solartron 7150+ part 3: Verifying accuracy by turning the volume up to 600V

This video is part 3 of a series about the Solartron 7150+ multimeter. It shows the tools and methods I used to verify the accuracy in each mode and range to find out if a calibration was needed. In this video I cover how to build kelvin probes to do 4-wire resistance measurements, test setups to verify millivolt ranges and hundreds of volts for the 1000V range and, how to do the same again but now for AC at 400 Hz.
