Digital multimeters sucks
This is no more then crap toys

I`m going with my analog one for four decades
No batteries

That is difficult to distinguish from a (poor) troll. Not good.

OP, did you try to install the firmware update? It should fix the issue you are having.

Different tools serve different purposes and understanding how a tool (DMM) works by reading the manual may help. If you can stand dead batteries on ohms, loading of circuits on volts, and low accuracy, an analog meter may serve your limited needs.

Sounds like someone has thrown their a rattle out the pram or should I say DMM.

Can an analogue  meter survive a metre drop?

Turbos suck even more.  Nothing but crap ICE use'em.  3-phase induction motors FTW!

Obviously the OP never uses the resistance ranges then, so a simple battery tester might suffice [emoji23]

I love retro-electronics, which also means analog multimeters. I recently purchased one in Tokyo's Akihabara district.

But other than to use them to null or calibrate a circuit which uses trimpots, really a DMM is a far superior tool.

True, their batteries go flat, but they last a looooong time. And most DMMs have an auto-shutoff feature anyways.

The batteries on an analogue meter for the resistance ranges will also go flat in time so where's the difference between an analogue or a DMM in that respect?

Let me guess: you blew one of your DMM puppies with your HV power supplies? Or the mention of batteries indicate you had a major leakage problem?

I hope it wasn't either the 87V or the 117.

The funny thing is, I use a Simpson 260 as my "Monitor" on one of my LTZ1000A reference.  Turns out my reference is pretty solid according to the Simpson!

an 8.5 "needle" analog meter split into decades, it will be quite the picture in the LTZ thread for sure.

Ill put one up when I get home later today.

Can't measure ohms without batteries! Simpson 260 on R x1 puts out 130mA! Great for finding poor connections.
It's the batteries sagging, drifting, keep turning zero adjust. Yuck.

Digital multimeters only burned me once- measuring mains voltage and I got good V readings due to leakage currents. An analog multimeter read zero. Would have saved me hours.
Low Z voltage is an important feature.

My stupid DMM has misspelled "pluses" and they still haven't released a firmware update  :-BROKE

Not always. Often changes and noise are easier to interpret on an analogue meter. Hence life-critical instruments are often have analogue displays, e.g. altimeters, ASI indicators and artificial horzions.

If I'm just noodling around a circuit to find gross faults, it is often faster with an analogue instrument.
There are lies, damned lies, statistics - and ADC/DAC specs.

My Simpson 260 Series 6 has two batteries for ohm mode, but one of which is also required if you want the overload protection circuit to work.

Perhaps the real issue is the user, not the DMM.  ::)

Multimeters aside, is the OP trying to reduce the information signal-to-noise ratio of the forum again?

Which battery are you referring to? 1.5V or 9V. Real 260's use a 22.5V battery  :-DD

It's the 9V. It's right in the schematic you posted. Yeah, this one isn't uber vintage. It was my dad's, though, so has sentimental value, even if it uses batteries I can still buy at the drugstore.

There are a few others here too, but not very many. I'm sure you have your candidates; I'm not going to draw attention to mine.

The forum rules are sensible - and are reasonably enforced by the moderators and members.
