Voltage Drop

Are we going to talk about RF getting into DMMs?
The DMMs I've used can't be used on tractors or under the hood of cars not even on the battery, because of ignition noise.
There's a lot to be said for old school needle meters!

Re: Voltage Drop

Truth be told, I don't think so.
I use almost entirely low end consumer stuff, mostly because I blow up at least a meter a year two, when I put the 10A scale across a storage battery,
The 750VDC scale across 2KV, or 400V to the low Ohms scale. When it's a free harbor Freight meter, I don't lose any sleep!
