Good to know... I've seen with mine set to DC the results can be inconsistent, as the sampling period doesn't handle square wave forms very nicely. With AC, I've always seen decent results for quick testing. It just goes to show that testing I might do for a team in their pit can't necessarily translate very well over the internet!
