Being an electronics tech myself and using 8 digit meters on a daily basis, the 87 is a good hobby handheld, but I like the old Fluke 8060a's and the newer Fluke 189's.

So what is the burden voltage of those meters at that level? Edit: The manual doesn't even mention burden voltage ..... (not surprised by from a big box store), just an accuracy of 1.2% - plus/minus 5 digits. Burden voltage and accuracy are a huge concern when you are down in the micro amps...

Hantek has some decent onces also.

Silver solder and 3 dimes took care of some holes in the bottom of a Honda Magna gas tank.

Your best bet is either the pc route, or, you can look for a local sale on a Snap-On MT-1665 scope. The MT-1665 has a lot of neat functions on it. Will Post screen shots of the one that I have in a while.

You might want to look at this before buying anything it discusses the burden voltage and the affects of it on current measurements, especially at the levels you are talking. http://www.eevblog.com/projects/ucurrent/

Get a Triplett 630 off the bay for cheap. 60 microamp range. That in addition to the customer seeing an older analog might be more convincing.

Thanks for the reply! I kind of thought that might be the case.

Picked up a Larin HNY-6000 floor jack for 10 bucks. Really nice shape, low on fluid. Added fluid and it pumps up pretty nicely when using the handle. Question is about the foot pump. Does it only serve to pump the jack up to the load, or should you be able to jack the load up using the foot...

This.

I bought one just like the one in your picture that is only marked "cornwell usa" at a local swap meet this weekend for 12 dollars. Stripped and thoroughly cleaned and lubed it. Works like new now.

Picked up a set of these off craigslist for 15 bucks. The picture shows one with the top of it at 25.5 inches from the floor. They are marked "5T". Anyone know who made them?

I picked this kit up because it was pretty much complete less a grinding bit. Would this set have a "credit value" on a Cornwell truck? Any thoughts on it?

I've got a Sun 1011 that the scope doesn't work on. I've not had a lot of time to mess with it other than check voltages from the supply. I'd love to get it to work, but am probably going to haul it off and use it as target practice since no one seems to have schematics for it.

A simple 555 timer circuit would do that for you. I have a Sun 1011 that needs some circuit boards. I'd like to get it working for the use of the scope, but since I've not had much luck with it, it may end up being used to target practice.
