Show your Multimeter!

[gamalot]

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..
bottom HP3458A (reader's) and my 4920M jump on the train with me tomorrow, to travel 170km for little Taiwan calibration plugfest meetup. 

"You are the last one"

 

[M. András]

the fluke was bought back in 2011 if i remember right
the testo is new like 2 weeks now, its small enough to carry around in a toolbox

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

You can see that it's not feeling well by the way it's laying bellys up.

[slurry]

A few.. and i also have some handheld, like Fluke 289, 116 and 101.

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

[joeqsmith]

I like the little Hansen meter.

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!!

[BFX]

Nice vintage but still working Metra DU20 (1969)

A new arrival, has a 619 brother.

Keithley 5900 (is a relabeled DANA 5900 with some cosmetix at the front plate )
this oldie requires 25 to 30 minutes warm up time to find total zero

Grundig RV3 (Classic VTVM) 
Grundig 6062 is the same but some little differents
Sennheiser RV55 (also sold as Grundig RV55) is a glowing AC only mV+V Meter with a bandwith of 1 MHz

[Vtile]

What is Zin for those old VTVMs I always wondered (I know it is high, but how high).

What is Zin for those old VTVMs I always wondered (I know it is high, but how high).

It just depends on the input voltage divider.  Tubes in general do not have a higher input impedance than FETs.  The claim to fame for a VTVM is that it does not have the low input impedance of say a 20,000 ohm/volt analog meter.

[Martin.M]

the RV55 have a 1M 20pF Input, so it likes Probes from Scopes.

Z in, = Sennheiser ZP2

My most beloved meter atm. straight from the 70..80's Poland. Have only BNC connection and one banana for grounding. I have two units, another one is in better physical shape, but this one is "spot on" through voltage scales.

As this have 100 Megs input in all DC ranges it is actually a picoammeter also (while nA is as low I have gone so far).  What I have found really nice for my odd hobby metering is the center zero selection, which splits the sensitivity range to half (negative and positive).
I wish I had the original "Radio Frequenzy Probe" since the HF button allows measurements up to 1000MHz with it (1.5 - 15V + 250DC max).

Anyway big claims on the "The only meter a laboratory need." isn't too far, really versatile meter and I suppose it is one of the best of the FET analogs there is (outside the big boxy benchmeters / metrology stuff). Also exported under Marconi and Conway brands. Uses hybrid amplifier.

ESD clouds around a room are real!!

Here is my little collection:

Part 1:
- Rohde & Schwarz Nixie Tube DMM UGWD BN 1110 - repaired, needs some calibration
- Keithley DMM 7510 - calibrated Dez. 2015
- HP 34401A - calibrated Oct. 2015
- Fluke 8520A - repaired (some Tantalums had zero Ohms. no good), needs some calibration
- Schlumberger Solartron 7065
- Fluke 3330B (well, this isn't a meter    ) but my repaired calibrator. Currently I'm working on a more stable reference source for it
- Brymen BM869s, purchased Jan. 2017

Part 2:
- Rohde & Schwarz Vacuum Tube Voltmeter URU BN1080, repaired, needs some calibration
- Rohde & Schwarz Nixie Tube DMM UGD 51

[Saronni]

Here's some pics of my trusty Fluke 75 while it was open for a battery change. A long time ago it was connected across a 12V SLA battery with the probes in the 10A current sockets.
