Did you know that the Thurlby 1905a has a 6.5 digit mode? Press [**] then [51/2] to enable it. I recommend using the filter to help stabilize the last digit.

Yes, I do.

I am not sure how accurate the 6th digit is. It was probably never engineered to be a 6 digit meter.
I have powered mine up and will compare with the 7150Plus.

My problem is that I do not have a reference with low enough noise to get definitive results.

There are few more abandoned cold Keithley 2001's in the another room. This one already look like disaster big enough.



I know you guys will hate me..

You will have all that empty space without the 3458A on your way back. Make sure you fill the shipping container with more goodies to keep that 4920M secure.

Oh, it is definitely not a 6.5d accuracy meter. No matter how many digits are shown, it is still a 0.025% accuracy meter at best. But precision != accuracy. I'd be curious to see how linear the ADC response is especially at the 7th digit.
Still, the extra precision could come in handy for comparing two similar values within a short time. Here, absolute accuracy and drift don't come into play, just repeatability on a short time scale. An example application is measuring rail voltage at different points on a PCB to try to narrow down the location of a short circuit.

The 6th digit on the 7150plus is very drifty/noisy so it's of limited use, but it's fine if you treat it as a 5.5 digit meter.

I must have missed something...

There was an earthquake in Taiwan?
It must be a heavy one: There is even an australian style Keithley...   :wtf:

I had these 2 cute Japanese meters already a few years but now I finally cleaned them up, checked calibration etc and made some tear-down pictures for my website. I can not find any information about the two Japanese meters. The first is a Yamato 100L from 1965. More pictures http://www.pa4tim.nl/?p=5784


The second a Hansen SC, more pictures: http://www.pa4tim.nl/?p=5801


The next is from the USA and part of a tests
et. I do not have the complete set but the meter itself is from 1944 and beautiful made. http://www.pa4tim.nl/?p=5803 for more pictures

I'm just nervous that that 3458A on top is going to fall down.

I like the little Hansen meter. 
How electrically robust is your meter?? http://www.youtube.com/channel/UCsK99WXk9VhcghnAauTBsbg

Here's my ageing multimeter, a Maplin White-Gold WG022. It's over 20 years old but only on it's 3rd battery (No backlight and a good auto-power-off)

Hey, I've got one of those too, maybe a couple of years younger and minus the holster, an irrisistable special offer deal.  Nice reasonably accurate meter, High-Z input on the lowest ranges too. The only problem is that the autoranging is slow, so it tends to go into bleep meltdown on fast changing voltages. Curiously, although mine is exactly the same WG022 model number its maximum current is 10A - maybe they found that they were pushing their luck on the PCB traces. Nice to see that yours is still fused though.

Here are a few I have on display and sometimes use for various tests.
I have quite a few that I use in the workshop, lab and take to the college when I teach :)
I went thru a stage of buying multimeters so that I would always have a spare.

Kinda think I have reached saturation point.......Nah!!
