 		Im new at this what is a good way to build something to read high volts, ampes, and be able to scope the wave form. Oh yeah without buying super expensive equipment.

 		Digital Multimeter or those bouncing-needle panel meters can be had on-the-cheap.

 		I wasnt aware you could get multimeters in the 40 kw scales.
I know power utilities had meters .

maybe i stated the question wrong how do I read volts up 100kw on my multimeters and oscope ?

 		here is a handheld meter that can measure 300 kW and


here is a probe for a multimeter to measure 50 kV

 		For current, if it's AC you can use a current transformer or a rogowski coil, both of which can be made cheaply. If you're measuring DC, you can use a very small value resistor and read the voltage drop across it.

 		Thanks guys for the input. It is greatly apprieated. Im trying to build a test station, but all I found was meters that went to 500 v ac

 		You can build a inexpensive HV probe to be attached to your multimeter. Here are a few links. (google is your friend) Try searching for subjects like DIY HV PROBE, DIY HV METER. You can also search HV probe on ebay (make sure to exclude -oscilloscope to limit the search). There are usually a few independent probes with meters built in. Also, I believe that fluke has a probe that attaches directly to the multimeter.

 		I have the fluke probe and it fits right in your meter! At least mine that I got at radio shack. I bought mine on eBay for $15 and it's worked great so far. Good to 40kV.

 		"I have the fluke probe and it fits right in your meter!"

A good rule with Fluke instruments and very high voltage probes is to make sure they belong to those paying you to use them !

My Fluke 87 hides in metal case and lives to see another day.

 		I hear ya radio tech. i think i accidently got over 100kv . The arc jumped about a foot and got me. "I pissed myself and forgot who I was for a half hour"...lol
I has messing around in the hertz freq so I figured when I hit the kh i better have a better plan.

Just kidding about pissing myself.
I used the one hand rule

thanks odium 45 just what I was looking for . I searched like crazy on bing no luck I guess Im going to have to range out.

turkey9 Im a mechanical designer, so when no one could answer my question I went back and had to reteach myself electronics. Havent used it for 25 years..lol
so I keep my flukes and oscope safely in the box too, til i figure it out with cheap meters.

Its changed alot since the old tubes....lol
