A Keithley 26220 picoammeter seems to pass some simple testing AOK.
Now I just have to fabricate some test leads that don't act like active antennae. some hints or tips would be appreciated and perhaps knowledge of a manual.

Sorry forgot to introduce my self, just an aging hobbiest trying to keep the gray matter gray.

It might seem all fun to own now, but who's going to look after it when you go away on holidays? (Me, me!!)

You're the one that snatched the 3458 from Bazos?

Unrelated to electronics but it's been on my want-to-get for a while: A Midas Pro2c + DL251! I will photograph it when it arrives early next month

NICE!

What do you mean not related to electronics? It's full of interesting electronics. Don't turn it on...take it a part! 

...just kidding...

Are you gonna set up a music studio or something?

Hahahaha

I run a small side business as an audio engineer and I have a regular gig for a choir. I used to run an LX7 as a summing mixer and do FoH and monitors off of a Soundcraft Si Compact. Two fat multis to stage, two mixers. Now one mixer and two CAT5 
I will get an etherface for recording and virtual sound check though

That sounds really great! Hope the Midas Pro will serve you well for years to come. Good luck with your side business!

Looking forward to seeing your repair thread about it.

Looks like a straight forward, no-nonsense power supply. I like the user interface. After a fix, she's a winner. =)

Lots of components arrived from farnell & TME

Very nice. I'm pondering a Y407810K0000V9L myself.

@Nx-1997 Some of that era HP test gear may be some of the most durable test equipment, HP released real manuals, they were pretty well made, often no ASICs and they are often full of parts that you can still get

Hi Remi,

Here's some info.

GPD-3303S Service Manual:

I just bought one of these new; $400.
The adjustable supplies (ch1, ch2) work good.
The 5V supply (ch3) works but has a 9.2V 50uS spike when the output is switched on (see image).
This occurs when unloaded and loaded.

I don't like this. I wonder how bad it is. Will it damage circuits it's powering? It's a very narrow pulse (low energy). Does anyone have an opinion on this?

Being in UK, I would be intersted in this one

Thank you for the information Gary. I should receive the unit today, I will keep you updated with the repair and the tests to see if I have the same overshoot on ch3.

My GW Instek GDM-8251A multimeter was just delivered today

This is from that huge blast of equipment from the ITT bankruptcy. If the chip numbers are actually date codes, it looks like it was made no earlier than 2010. And it was only $120! This is one of my newer instruments. Most are 20 or 30 years old.

Cool beans - several of us here have acquired these meters. Seems like a decent DMM on this bench. Check the firmware - if it's not v2.3 you can get the new version from GW Instek tech support, just send them an email and ask for it -

services@goodwill.com.tw

PS - but you will need a GDM-01 USB cal key and a serial cable to perform the firmware update.

My meter has the 2.30 firmware. I compared it's readings with my HP3478A meter. Calibration looks good. My GDM-8251A meter did not come with the cal key. I'm now debating whether to buy a cal key just in case I need it later. A few years from now they might be expensive or not available.  I doubt that there will be any more firmware updates for this meter. I might need the key to recalibrate it at some point in the future.
