Yes I had. I believe your site has more about the meter than the sum total
of the rest! I was surprised how little information there is about the
meter available.

I downloaded the user manual, but not the service manual. I will give this
some more consideration. I can get the instrument for 600 Euros + shipping
from Germany, so its not a fortune, but the issue of calibration is
concerning me a bit, as is the fact that a few people have sent me emails
to say they are noisy and slow.

I wanted to make some low-resistance measurements the other week, and was
considering getting an Agilent 34420A. I'm wondering if that might be a
better investment.

Of course, it would be nice to have a 3458A and a 34420A, but that is out
of the question due to the cost.

Someone else sent me a private email, and gave me there name too, so I have
sent an email to them.

I can't drive as I'm epileptic, so so you are not quite as easy to get to
as you might first appear. I guess it can be shipped easy enough.
