Re: How to calibrate a voltage meter
YMMV. Right! Note especially the difference between the two Flukes!! The other two were a BK Precision multimeter....about $50....and a Velleman...about $20.
I like the Vellemans and generally calibrate them @ 12VDC to my Fluke 189.
Lesson: it's dangerous to assume that your multimeter is accurate, unless it has been somehow calibrated.
