I think Tenma is just a name. See the post about the "hung chang" scope or whatever. I got one of thoise and really, it's not bad. It's only a 20 Mhz but it is fine for general audio work. It triggers OK and there are no funky abberations in its operation or anyhting. It is at least as good as the B & K.

I also have their soldering station, you would probably would recognize it under several brand names as well. Hey, it works and is works well. Sooner or later I'll have to get a Hakko or something, but for now this is just fine.

If the price is right, and they accept returns, what's to lose ? Somewhere you should be able to find some precision caps and coils to test. If the thing reads within reason, there is no reason to be picky about where it is built. them days are over.

the time to worry about where things are built was back in about 1978 or so.. When people bought the Sanyon TV for $239 instead of the Zenith or RCA for $279, they spoke in the loudest voice possible to the manufacturers. Cost is King. The manufacturers responded and now none of these things are made domestically.

That forty bucks is what happened to the economy.

With the cost of what we have to service dropping, cheap test equipment is a good thing - for the bottom line.

I see how using 1 Khz could be not quite optimum for these measurements. Depends on the range. For RF coils, and caps down in the low PF range, I can see problems. But then if you kmnow the limitations and the pricce is right - go for it.

If you can play with it for a month and send it back, I say you got nothing to lose.
