I am looking for a good talking multimeter. I have one from china and there is no button on the probe to announce the reading and it is a pain to use thanks.

I just found this site---they have a Protek talking multimeter:

(scroll down---it's right after the calculator)

Does it scream if you overload it?

Timmy1 see The meter in your your last post viewtopic.php?f=8&t=176668


I used the NEXXTECH 221-8202 meter in the Fall 2013 session of the Kelly Creek Community School Electronics Program and it worked just fine.

An additional feature is a bright LED on the probe that lights up where you are taking the measurements
if you have some sight for this.

These meters are inexpensive, but the weak point is the button probe, so if find a used one, makes sure
the probes are not worn out. Thew meter has a clearer voice than the two older Microntas I have here.

If you can find a Radio Shack with any stock it might be wise to grab a few of them.

Are you still working on generator electrical systems ?

I have a Micronta 22-164 talking meter and when I put new batteries it says change batteries nomater what setting the dial is set on so I figured it is a faulty part but not sure which part.

First time I heard of a talking volt meter. I think it would drive me nuts. I tried to use a GPS once and had to turn the thing off.

I have two 22-164 meters. One works fine. The other says change batteries despite being fed
the correct voltage to the PC board, independent of he batteries. Until Timmy1 mentioned it.
I haven't touched them in years, There seems to be no data from Radio Shack support for that
model.


There was something odd about the operation of the bad one and I will try and find out
, hopefully without destroying the good one too.

These talking meters only talk when you press thew probe button.

However, they may annoy others, working around you. Perhaps people know that.

Steve that would be great if you find out what causes that problem.

Some one told me it might be a bad internal memory battery in the meter.

Might be a Radio Shack ploy to get you to buy more of their batteries.

Are the battery terminals on your talking meter corroded or dirty; if so then cleaning them might help alleviate the problem.

Does any one know where I can find more information on that meter?

It's possible that a component drifted out of tolerance (most likely a resistor). Perhaps steve can measure the values of the components in his voice meter that is experiencing the same problem.

The picture helps a little but it is not very clear. What is the large sky-blue part at the bottom center? A back-up battery perhaps?

I saw a nexxtek on ebay for $50 but I imagine you would rather fix this one.

Maybe one of us would take a look at it if you could ship it? I'm not too familiar with the design, but can spot a bad part as well as the next guy.

Ed I can't tell the blue part I am blind but I think you are referring to the rotary dial switch a square large part? there is no backup battery in it.

It's just below the rotary switch. It just seems to be of a large size for typical parts in a multimeter. Might be a large capacitor, but I was guessing or hoping it might be a backup battery that failed. A relatively easy fix if so.

I actually didn't realize you have vision issues until I read one of your older posts about a capacitor meter back in 2011, referenced in one of your more recent threads.

I'd volunteer to look at it if you're able to mail it to me. I am used to not having any schematics or service info for things I tinker on. It may have a bad part that is no longer available, but it could also be something more easily repairable.

Thanks Ed that would be great. I know the part you are referring to now it looks like a resistor or capacitor. can you pm me your address thank you.
