I haven't seen a response to you yet. But, from what I've learned with my experimenting. There is NO meter unless you spend money. An oscilloscope would be ideal, but for what you and I want, the only option I see is the RampMeter. And I am so frugal, I refuse to pay that much. I do use a regular multi-meter to check voltage. But even that is not accurate. It's only a close check. And you can forget measuring amps. I haven't found anything that works. Not even my multi-meter that measures both AC and DC amps. It simply don't work on DCC.?????????????? Morgan Bilbo, DCC since 8/18. Model PRR 1952.
