Alright, long story short I've reached a point where one of these would be dang useful, since there is little information out there about building them and they are REALLY expensive, I come here.
So, I start with a 10 volt DC meter.
Then add a rectifier, calibrate, add switch, and bam. It measures AC and DC.
Then, add a 10:1 voltage divider, so it measures 100 volts.
Then, add a 100:1 voltage divider (or a 10:1 on top of the existing 10:1). 1000V
Then, add a 1000:1 I can measure 10KV
Then a 10000:1, I can measure 100 KV
and, the kicker, I would like to be able to measure up to 1000KV (X-ray transformers rate 140KV, and go higher, and theres marx generators and CW's and other stuffs, but this isn't about that).
With a rotary switch to select one.
Basically I end up with a GIGANTIC 1.21 GIGA OHM (not sure what resistance actually) resistor string tapped at various points, and a rectifier for measuring AC.
So, does this sound do-able?
Does anybody have any advice, words or wisdom, or anything that would help out with this at all?
