Re: ordered one of these, supposed to read 1kv directly

BTW: if you can find an older Fluke 8060A DVM's they can measure up past 120 M ohms so checking resistor divider chains are simple. Many DVM's can't measure

Chris: Some cheapo DVM's aren't even 10 M ohm input inpedance. I beleive some of my HF DMV's are 1 M ohm input. If you have a donor CDV715, there are some +1 G

Careful with one of those china meters they have no protection not even a fuse {just 2 tiny resistors} Dont ever measure amps with it. I have a KV 1-40KV probe
