Maybe a logging multimeter could be a ting?

Computer sceens are big after all.

Yea
I see some universal datalogger project at this forum
But it die isnt it?

won't the backlight on an LCD screen help?

No
All LCDs suck then You 65

And my Fluke LCDs suck too

I'd go for a handheld like the UNI-T UT61-B or one of its bretherens. It's cheap enough and via its RS 232 interface the display on your PC will definitely be large enough. . Maybe there are cousins of this DMM with an USB interface. Just look around.

I think about UNIT
but actual software if full of datalogging advantages and digits not quite big
Does anybody build some custom software that translate digits to a full screen mode only?

With "Profilab" it will take you just a minute or two to get a 72 pt readout. See pic enclosed. Also "Profilab" has a module for the UT 61E. The main drawback of "Profilab" is the limited number of drivers/modules. So you should first consult the hardware compatibility list for "Profilab".

P.S. The point size list ends at 72 pt. But by entering the point size manually, you can go even larger. Just sucessfully tried 200 pt which pretty much fills the screen of a 17 in. monitor. Font height is just under 6 cm. Large enough?

We did develop a technology called glasses which seems to help many people but in the case of the OP, one has to wonder how they are able to read the computer screen and post with a claim of such poor eye sight.

Venerable Fluke 8010A may be within reach.

I'm disagree. You seem to be able to find fault in everything.

[Nusa]

What about 6USD at czech market for vintage German DMM marked "G-1002.500"?

In working condition, that sounds like a hell of a deal to me.

The key is the amount of time you need to refocus. For big bright numbers this is easier than a small non-backlit LCD.

I posted an example of a big LCD, I also have difficulty reading but you would have to be blind to not be able to see the display I posted.

I don't think the problem is the display that's the problem here.

1. All LCDs suck

2. 4W resistance measurments
   0.5% acc is ok too
   I think that 5% accuracy is ok too
   In fact, I`m happy with simple 3 1/2 meter for $3
   I think about UNIT

3. fool proof

1. is Personal preference
2. Does not make sense (the kelvin probes alone would cost >$50.00) and WTF are you doing 4W resistance measurements for if 5% accuracy, 3 1/2 digit resolution is all that is needed.
3. How much engineering are you expecting in your bench meter for your $50.00?

[janoc]

If your only issue is the display readability, then there are plenty of cheap handheld meters with large digits and/or OLED displays. For example some Extechs, one of the recent Anengs, etc. That is likely going to be a better option than either an utter crap new or a (very) beaten up second-hand bench meter ($50 is really too low to get anything decent when it comes to bench meters).

For $120 or so you can also get the Mooshimeter which can use a phone or tablet as a display (and runs circles around most $50 meters) - so buy a tablet as big as you need in order to be comfortable, problem solved.

4 wire resistance measurement is pointless on a meter with so low precision, only the higher end instruments have that.

hey boys
I KNOW WHAT I`M LOOKING FOR
but I don`t know how it is called 

It is not ANY handheld and LCDs models. I have handheld Flukes  yet.
Now I`m go with this basic RFT meter. It provide me all that is I need

BUT! Idea about translating display to PC is ok too
Does anybody run this program? https://www-user.tu-chemnitz.de/~heha/hs/UNI-T/

[joeqsmith]

It must be one of these.

no leds
no 4W

silly joke 

[coromonadalix]

It must be one of these.

+1  good one,   here in quabec Canada, some CSA inspectors still use needle meters for leakage tests  lolll

[001]

trolls everywhere 

Why do You recomend me things what I use for a decades?

[beanflying]

It is very hard to be serious while you seem to want to maintain unrealistic expectations on price. Unless you are prepared to consider at least double your budget plus some freight to get even a fairly poor secondhand bench meter then this topic is a WOFTA bandwidth.

Hi

Commie gear is almost free at Europe now

[beanflying]

If it suits you then buy it. Really unlikely anyone here will ever have seen or used one so you either take a chance or look again.

And my Fluke LCDs suck too 

How bad are your eyes really?  I have a Fluke 27/FM and the LCD is very readable to me and I have been wearing glasses for over 50 years-bifocals now with bad vision in 1 eye.  I am 62.

Are they using an analog clamp meter like this?

Hi

You would be pretty badly mistaken, lot of that gear are collector items (especially if it is working). Also finding something in good working order is like searching for a needle in a haystack. Most of that stuff has been thrown out after the 1990 when better hardware became available. In addition, do keep in mind that depending where you are, the postage on these items alone could be more than your $50 budget - e.g. the East German meter weighs 4kg. Sending that e.g. to the US would be really expensive. Oh and it won't work on 110-120V neither, no such BS in the former Soviet bloc, we had everything designed for 220V only ... 

Also good luck trying to find components if something breaks in it - keep in mind that we didn't have access to western components. So what you are going to find inside are obscure "commie" parts, in the best case straight clones of the western ones (e.g. 7400 logic), in the worst case a custom Russian-made chip that is a complete unobtanium. I have found a schematic of this meter online and it seems to be a mix - 7400 logic + obscure, specific parts, such as the main IC controlling the entire meter.

Nobody serious is going to recommend you a meter like this, even less so because most people here aren't familiar with this gear.

I've just spotted a whole bunch of HP 3466A 4.5 digit DMMs on Ebay for $50 (ex. shipping).
