"Analog" DMM?

[Johnboy]

I've toyed with pulling the trigger on one of these for nulls (none of my meters have a bar). After glancing at the unusual specs claimed for this thing, I suspect the movement is IC-driven. Anybody got one to confirm?

Of course, I forgot to specify, sorry.

I wouldn't bet the movement is driven by a D/A converter tied to an IC.

Which specs do you find unusual? Our 1960's ICE Supertester 680R had a 50µA movement and included all these functions plus frequency meter.

The meter looks rater conventional, including the nonlinear ohms scale. So I don't see a reason to have something digital included.
There is also the option to just use an amplifier - usually a pair of JFETs at the time.

I one though about a slightly digital movement with a stepper motor - but this was for large size. In cars there are sometimes such movements, that stop when power is off.

It's hard to say for sure, but I think I see a standard D'Arsonval movement behind the prism around the zero adjust setting.  None of the specs on the meter look out of place for an analog instrument.  I have both analog and digital meters on my bench.  The only things I miss on the analog meters is autopolarity and autoranging.

The meter shows 20k Ohms/Volt as the input impedance on the DCV 0.1-50V scales and that is usually taken as full scale volts.  50V full scale would have 1 MOhm input impedance.

I think this is an analog meter.  I like it!

ETA:

I chased this down and it is indeed an analog meter.  I like analog meters so I bought one from Amazon.  I also chased down the Resistance Zero Adjust.  There is a knob <somewhere> as there is on every other analog meter.

I know only of Sanwa. Some of their meters have autopolarity as an additional feature. For example EM7000 (have autopolarity on both V and mA), SH-88TR, YX-361TR. YX360TRF and SP21.

There might be others from different companies, too.

This reminds me of the advertisements that blanketed our local radio stations a number of years back, when MMDS (pay-TV over microwave link) was popular.  They said it was the new thing... "wireless cable"!  I honestly don't think they caught the irony

Kind of like the analog scope adage that you should have if you can get one cheap...

I saw a Craigslist ad by a retiring electrician for a spotless Fluke 87V and an equally nice Simpson 7-M. The 87 was listed at a fair price, but the Simpson was $20. It was a 90 mile trip each way and my wife looked at me like I was nuts. When I got there I fully expected him to say it was a typo and should have been $120, which I had in the other pocket   It was that nice, case, probes with screw on alligator clips. I still pinch myself every time i open the case to use it. Wouldn't give up my DMMs, but I really like the way a good old analog meter reacts.

I have once repaired analog meter with auto polarity - actually more like true RMS (with an AD RMS chip) and polarity indicators. So no switching between AC and DC, just the ranges. I don't remember the brand, but it was a little larger one for demonstration use (e.g. school).

There where a few old Siemens combined analog and digital multi-meters with both an analog movement and LCD with digital readout.
