cheap Asian text equipment

Apr 25, 2012 15 Replies

I was browsing eBay for cheap multimeters, and found this in the description of the Vichy [sic] VC99...



"Dual-slop DC/AC converter..."



Must not be very accurate.



Anyone have opinions about Vichy products (other than the water)? It seems Vichy is trying to suggest Vishay, a well-known manufacturer of high-quality resistors.

I like the freebie Harbor freight coupon digital multimeters. For what I need they are fine, and I don't have to treat it with kid gloves like I used to do with the expensive voltmeters we had at Bell Laboratories where I worked.

The Vichy is interesting because it has functions that one rarely finds on inexpensive DVMs.

I have one of the Harbor Freight DVMs, which I carry in my toolbag.

I had to prod around in a machine that uses 208v with a $5 looking multimeter recently.

I was pretty concerned about the entire thing having a solder blob work loose and throwing the thing into a current range and exploding and taking off my hand and face.

two things to know about the $3/freebie HF DMM;

1.input Z is only 1 MegR. 2.the input jacks solder joints crack and become intermittent.

You must have been there at the very end--before 1984, a fancy DMM wouldn't have been visible above the noise at Bell.

When I was a postdoc at IBM Watson in 1988, a colleague was thinking out loud one day about buying a fancy lock-in amplifier. "Well, it's stupid to buy one, and I probably don't need five, so I'll order three." Bell had money to waste like that too.

I forgot one of the most important things; the first DMM I got read VERY high,a 1.5 volt cell read almost 2 volts. the exchange DMM read much closer to 1.5V.

I worked at Bell Labs the Summer of 1970 -- a terrible mistake. Anyhow, they spent money like water.

They may have had a monopoly, but at least they knew how to give great customer service, so I personally didn't care. Even knowing the service cost more, overall, still didn't care. Interesting, eh?

If they did, they lost the knowledge. AT&T is one of the worst companies you could do business with. They just don't give a damn.

Thanks to judge Green, we don't have that black corded dial phone on the wall anymore. Ok maybe a little facetious, but my parents had the same phone for

35 yrs, with a few extra turns on the ringer coil I added when a teen, to trigger some unremembered project. Mikek

that was way back when, not now.

half of that is in the probes alone.

assuming they were even soldered correctly to begin with.

So the most improbable thing was wrong with the machine. Not one, but two open heating elements, and the spare from the spares kit was also open.

Instead of trying to track down house marked west german era immersion heaters with strange bends, we're looking at having custom ones made here. I can't wait to see the quotes on those things.
