So nothing really radical. The higher class DC coupled meters would be fine if using their voltage function but their cost is really the issue?
I need an AC-Coupled meter (ACV and ACmV ranges). 1000V DC, 750V AC, w bar graph. A higher class DC coupled meter with adequate resolution would be nice but I don't really think that I'll find a moderately priced one.
Cost is the issue because I don't need any advanced features and I will need to buy at least 2 of these because I have 2 work benches.
Presently I am using a Radio Shack Smart2 bench meter that I bought in 1995 for under $100.00. it does everything that I need for this application but I want to replace it with a more recent model. I also had an even cheaper Micronta meter that worked well. All the DMMs that i have ever used have been able to measure ripple voltage, because I can only assume that AC-coupling was the norm then.
Here is a typical case:
1: The Patient (DUT)
2: DC measurement of First Stage of DUT Power supply = 440VDC
3: AC measurement of First Stage of DUT Power supply =~ 4.5VAC on meter, 4.6V on scope. This is 'normal' for this amp
4: I've had a request for a photo of my new Aneng V8 so here it is connected with a series de-coupling cap
5: DC measurement of Second Stage of DUT Power supply = 431VDC
6: AC measurement of First Stage of DUT Power supply =~ 285mVAC on meter, scope can't trigger properly because I need to use 100x probes when measuring high voltage. scope is only seeing 28uV. Notice that the Smart2 will autorange down to the 400mV scale, no need to switch to a separate mV range!!
7: AC measurement of Third Stage of DUT Power supply =~ 20mVAC on meter, insufficient voltage for scope, 200uV using 100x probe
Thanks again for all you valuable help
