Hello all,
Just a heads up. I noted there is a lonely Datron / Wavetek 4920M AC
voltmeter for sale on ebay, starting at US$650 (ending in 1 day !). I have
little idea of its true working state or not (picture shows it powered on).
If fully working it would be a good buy for an AC voltmeter
Charlie,
Did my reply to your question along with my lab temperature graph link come
through? Just checking as there has been some issues with the posts.
I don't like the feature where you don't see your own posts.

Hi Don,
Your post and link are fine but I need to get some time today to look at
it more carefully.
I had two posts recently that were blank but since then all seems back
to normal.

Charlie,
The Error Ur is an under-range error; you have to apply an input above 10% of
the range before it will display a reading. The 4920's are a very nice
instrument. Their only problem is that they are all so old that they are
reaching the stage where some components are drifting
Hi Stephen,
Thanks for the info on the 4920M. It might be that I should pass on this
but it is nice to know that it is probably working. If I don't have the
necessary items needed for calibration it might still be a good source
uncalibrated.
I was hoping that the 4920 had better minimum
