Yeah, before buying it, I downloaded the manual and confirmed that you can measure and display both voltage and current (AC or DC). Not sure if it measures simultaneously or interleaves but for my purposes it won't make much difference (though a loud relay would be annoying).  Either way, for the price I don't think I can go wrong.
It is nice it can do that but for some reason it can't display power which would be so nice for measuring efficiency of DC-DC converters.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Absolutely. It was a good score. :-+ I was just curious.

I couldn't help myself.  I snagged one of the GW Instek GDM 8251A bench meters on eBay. From the ITT auction I suspect. Many more listed. I was able to get it for $95 + $20 shipping.

I just nabbed one for $105. Do I need it ...

Um, well, ...  :-// What if I told you yes ...  :popcorn:

Yes, TEA - the answer to TGAS ( Test Gear Acquisition Syndrome).  What are those 12 steps again..?

Today i just filled the last spot in my 42U high rack cabinet by adding in a Gigatronics 6100 8GHz synthesizer that managed to repair at 2 in the morning. :-+
...
but i also scored a Tektronix pattern generator for 40 bucks on ebay a few days ago. :-\

For me it mostly started as getting the test gear i needed for a better price since quality brand new gear costs a fortune. But in order to find a good deal on places like ebay means looking trough a lot of pages and keeping eyes open, as good deals go fast, but along the way one keeps coming across other gear that you perhaps don't need right now but it would be neat to have. But hey all this test gear is useful for doing work and you can always sell it (If done right for more than what you payed for it)... tho i only ever sold 1 piece of test equipment so far (And lost money on it cause i bought it new).

Still better than collecting stamps (Tho they are easier to ship overseas il give them that)

FLUKE Philips PM3380B

I bought this scope on ebay Germany for Euro 100, the seller lives in 5 min walking distance to me and the scope is like bran new.
Came with all original accessories, also like new and the original glossy datasheet.
Has even the original screen cover and BNC to 4 mm Banana plugs

Once in a while we can get very lucky, I think.
I have several of these scopes already, but this was the best score so far.
There are 3 kinds of people in this world, those who can count and those who can not.

Thanks - the first step is to admit I have a probelm, I realize that now.  :palm:

If anyone wants some of the drug I got - here is the seller of the drug meter - they have more ... just look for the shady guy on the corner with the black trenchcoat.

Whereas the correct number of pieces of test gear is N+1 where N is the number you already have, I have been informed that one must also follow the S-1 rule where S is the number at which your spouse leaves...  Unfortunately S is highly variable and seems to be proportional to the number of visible items.

Hmm...
Avo 8
Up to 2500V DC/AC, calibrated in 2003 and still sealed, ex-military. I use it for battery tester and book stand.
Meets all safety regulations.  :P

Unigor 6e,
FET-VOM. 100 ticks, precision needle with mirror
1Meg/10Meg input AC/DC
ranges: 1mv to 1000V
ranges: 1uA to 3A
ranges: 0,2 ? to 50 M?.
ranges: 0,05 nF to 2000 µF
Burden voltage 1mV to 500mV

Meratester/Marconi-TF-2650/Convay 2x
FET-VOM
100MOhm AC/DC
BNC connection. This one shows the ghosts travelling around the house.
0 to 1 GHz (with prope that I do not have :(( )
Center Zero ability
Mirrored precision needle, 30 and (dang forget the higher scale) ticks
Resistance: 1 ohm to 10 Gohm.
Voltage: 1,5mV to 1500V
Current 0,15uA  :o to 1.5A

This is neat piece of equipment, made in Poland. I wish I could find the HF probe.

Fluke 8030A 3½ digit DMM.. Still in specks according the new Fluke I did measured it against when I had opportunity.

PicoScope 2204
FLUKE Philips PM3380A
Tex rebranded analog function gen. 0 to 11MHz
Some bit and pieces, soviet micrometers.  :-DD

FLUKE Philips PM3380B

I bought this scope on ebay Germany for Euro 100, the seller lives in 5 min walking distance to me and the scope is like bran new.

Oh. I have the A-model 100MHz version of that with Fluke branding. I like that I have both analog and digital in same scope.  They have "defect" that they get really hot just behing of the CRT and burn out. So might want to check if the cooling is OK in yours.

I was able to get it for $95 + $20 shipping.  It will be nice to have a dual display bench meter for simultaneous voltage and current measurements. Photo from the listing. Mine should arrive next week.


I just bought one of these meters. Likely from the same seller. The picture is the same. I sent a question to the seller asking if the cal key came with it. It does not. It's just the meter. I was also curious and asked if he got them from the ITT bankruptcy. He said yes, that's where they came from. I did some ebay searches and found a huge blast of GW Instek power supplies for sale. Most likely also from ITT. I wonder what other test equipment was in use at ITT? I probably don't want to know. It might just cost me another $120! or more! My existing bench meter is OK. I just couldn't pass up getting a much more modern unit for such a good price.

Ask an EE if he has too much test equipment in his home workshop and you get the same answer as asking an alcoholic if he has too much beer in the fridge :)

As you may know - the cal key is part #GDM-01. They are available for ~ $8 - $10. For example -

Not much of a personal score but I work for a state agency so we get to bid on surplus government lots. Boss ended up bidding (with myself and one other being the pick-up mules) on a HUGE DOD lot of "rejected" test equipment. Ended up with around:
~10 HP 8920 A/B Service Monitors
~12 HP 8562 Spectrum Analyzers
~12 Agilent 8563 Spectrum Analyzers
~20 IFR 1100/1500/1600 Service Monitors
12-14 IFR 2947 Service Monitors
Misc. HP signal generators/freq counters/power meters
3-4 HP VNAs with bridges (cannot remember models off-hand)
~10 Anritsu Spectrum Analyzers
2 Anritsu SiteMasters
2 HP 8935 Test Sets
and a crown Jewel - the Rohde & Schwarz VNC VNA that I am trying to repair (in the repair section of the forum)

We picked all this up across almost 10 pallets strewn with a ton of the HUGE pelican cases, some older networking gear, and some other bits and pieces.

The HP8935s have been repaired and put back to use (one calibrated and current), the power meters were all repaired and put back into service, along with a handful of the signal generators and freq counters. Both SiteMasters have been repaired, one with a cal and the other was rejected but close enough for field troubleshooting work, and a couple of the IFR 2947s have been repaired and put back into use (one of them being mine that I keep in my truck).

The Spectrum Analyzers I am vastly understating the number, and had to off-load them to another one of my transmitter sites to keep them all in one place. We repaired and use about half a dozen of them, and I am slowly trying to repair the rest and/or sell for parts. I hope to share some of the equipment and parts here as time goes on, mostly I need to 1) get all the exact model numbers and 2) get all the service manuals to really work on them all. HP/Agilent is great with offering service manuals online but all the other brands are terrible.

I assume this is needed to do a calibration?   I can find no info in the  8255A user manual. A google search also returns no info.

Any more info appreciated.

EDIT:  Ah, just found This thread here

What is the purpose of the GW-Instek Calibration key? I checked at the website from GW-Instek, but there is no description available for this item, so for me the purpose is unclear :)

It unlocks the meter to allow calibration. Since these came from ITT I can understand why the cal keys are not with them. Some bright student might decide to try and calibrate it using his $20 generic meter as a reference :palm:   Also the documentation that I've read says it's needed to perform a firmware update.  Once I get my meter I'm going to check the firmware version. If it's not current and if there are any important bug fixes I may buy a cal key to allow the firmware update.

Hmmm, I'm looking for the firmware but can't find it. If you go to their site here -

GDM 8251A

You can find software for the 8251A (the unit is obsolete now), and you can find the firmware updater program, but there is no firmware at all. I even unpacked the firmware updater and installed it, but it doesn't include the .hex firmware file (no, the Download button in the program doesn't download it from the internet, it downloads the current version from the meter). I also searched a few other sites to no avail.

We'll have to find it!  :-//
