I'm looking for a Multimeter that reads off its readings.
Back in the day Radio Shack sold the MICRONTA 22-164
Nice video of it in use on youtube http://bit.ly/2oY8gmH
Anything thing like this in production today?
I have a vision impaired friend I'm trying hard to find a replacement for.

I'm sorry, but I've got to ask - I'm guessing that we are talking about someone who is legally bind and therefor has at least some degree of sight, even if not much. but how can he place the probes in the circuit?

I was going to ask the same thing.

Probably uses some form of optics to enhance his vision of what he's working on, so he see's the probes, but can't see the meter

guns parts are always the same and easy to identify.

The parts of a gun don't have potentially lethal voltages running through them. Also, you can't discern the color of a wire based on how it feels.

My friend is a 100% blind.
Not "legally Blind" But fully blind.
He rebuilds vintage cars and trucks, in a garage with NO lights.

Has your friend used the old talking meter you need to replace on electronics, i.e.
transistor radios before ?

I hope he is using the multimeter to test wiring in cars and trucks and not high voltage circuits. I don't think it is a good idea to feel around in a powered up radio to find the correct test point. :roll: I would love to see some of his work. Amazing what people can do when they put their minds to it.

Today, I finally got the talking meter from the Ebay vendor mentioned above.

A few points:

It is a 2000 count meter.

It has a ball and detent selector.

Unlike the ones I already own, it does not have the button on the probe, for making it talk.

It has a button on the meter, that toggles the voice function on and off.

Once on, it will speak the value, and wait until the value changes, and speak the new
value. It has a clear voice.

It can speak the average or true RMS value. Whether it does, or doesn't have correct
circuitry to do this is probably moot with only 2000 counts.


The meter looks solid and should last if cared for. It won't last tossed into a tool box.

OK, so I got the meter in.
One tiny little problem, it speaks in Chinese.
Does anyone know how to toggle the Language?

I do have the instructions, they are in Engrish lets say. It mentions the button labeled True/avg is the selector for this function.
And I've tried lots of combinations with it.

Suggestions??????

My meter speaks English. I reviewed the instruction sheet, tried various
things. The button for the voice only selects true or average, and toggles
the voice on.

I bought my meter through an Ebay supplier.


Just a thought, some Chinese suppliers have a check box that
has to selected at time of purchase. Perhaps Chinese/ English
voice, as described in the instructions, is decided then before
purchase.

Contact your seller.

Perhaps you need to press the button for a second or so to change language?

I tried various button press tricks, including holding down the speech button, with the power off and letting it power up then, releasing.

Didn't work.

Perhaps today, I'll open my meter.

I have a feeling the processor for the Chinese or English version is
ROM flashed at the factory with the language table.
