Need Schematic for an Exact 7030

I think that is the same as 1000 Megaohms. :-) Mikek

Thanks. I didn't think such high values were needed but the list of typical applications certainly covers a wide assortment of uses. However, now that I think of it, I did have to deal with some giga ohm resistors in a first generation tube type "sniper scope" image intensifier. A finger print will ruin it, so it was rubber gloves and alcohol cleaner.

Exactly. The point was that many DMM's claim more. IIRC, my Tektronix boasts 5 Gohms.

I have a couple of HP3478A DMMs. They quote >10^10 ohms, 3V range, and below.

My venerable Keithley 610 electrometer is >10^14 ohms on all voltage ranges, (or it was when it was new).

1G input impedance has been pretty pedestrian for years.

I saw where you posted a "thanks" on that forum. Doing that helps the next guy who is thinking about sharing some ancient documentation. :)

Most unfortunately those Arduino links to the manuals don't seem to work any more, or maybe I am not authorised in some way. Do you know where I can get copies of the manuals now?

I think the administrators of that forum changed it from "open to everyone" to "open only to people who are members of the forum".

You've got mail (to your martinreekie gmail address).

Looks like your email is good, give me an ok and I'll send you a copy in pdf form. It is in two sections. Mikek

Since that forum has now been closed to non-members, these links won't work anymore. I got the brain wave to upload them to BAMA, currently at

. Whenever BAMA updates, they will probably show up at something like .

I recently got a 7030, all works well except for when i enable variable symmetry. Then the frequency divides by 1000. Is it possible you send me the PDF's too? They seem not to be available anywhere else on the net.

The address is: zinloos1 live nl

Thanks in advance!
