That would be encouraging.

I will amend my original statement and say that I would remain skeptical using a multimeter unless I absolutely understood how it interpreted DC voltage readings.

I recall (in my ignorance) looking at a pulsed DC voltage signal with two different voltmeters and getting two different readings. Eventually I bought a multimeter with "true RMS" capability that provided a usable value.
