About Posting a Comment

Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.

Author Name is a required field.

Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.

Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.

You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!

Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

That probe type is not safe if the power of the resistors is not appropriate. For 30KV the power of the resistors has to be of 4.5W and for 50KV of 12.5W. If one of the resistors breaks up can generate enegia peak that can damage the DMM. Resistor in serie with the DMM more MOV or gas spark gap are necessary in that circuit.

Depending on the neon voltage it will operate properly up to about 50-90 kV. I wouldn't trust the insulation above 30 kV myself.

Built better I'd use it to 50 kV. If the neon starts the glow it will be clamping the voltage and it will no longer be linear.

Please tell me how much kvs d.c volts your probe can test. thank you C. Persaud.
