Just read this 10 years after you wrote it - thanks for the write up! It was extremely helpful and obviously has a lot of work put into it! Rick

Lately I have been writing a lot more about multimeters:
Multimeter and component testing
Multimeter probes
Multimeter and voltage measurements
Multimeter and pulsed DC current (PWM)
Tolerance specifications for multimeters
Clamp meters magnetization, demagnetization and offset
Multimeters and current measurements
Multimeters and thermocouples

Multimeter design
Multimeter protection and safety

And also been reviewing some:
Multimeter selection table

Measuring >10 Amps without blowing up your DMM...
...by making up a $2 shunt!

How to test high DC amperage (500+) using a DMM by making a Shunt that measures Amps as millivolts on a DMM, brilliant video explains all!




Setup from video:

Measuring locations on cable shunt:

Verification with amp clamp:

My Fluke 88v uses this simple shunt (no clamp needed) with ease to measure 600+ amps 'as millivolt' readings on my car alternator and no blown fuses...
