Well, I hate to throw this thing away. I like it. But I have no ops manual and it has some features that require one. I've been all over the web, and every link to the "manual" only gives you 128 pages of sales information on other products. Go figure.

So I'm hoping someone has one of these $30 little gems with the ops book before I just buy something WITH a manual. It's not my primary DMM but it comes in handy sometimes to have two.

Thanks.

Well, if its the thing I found a picture of, its an awful lot like the Cen-Tech P37772. Which I believe is actually a Mastech M9508...

The (obvious) difference is the lack of temperature measurements. The case styling is too similar for it to be entirely coincidence.

Perhaps those two hints will give some further leads.

Thanks David. Apparently Steren is a wholesale manufacturer so maybe they make them all. I’ll figure it out eventually or it will take the final journey.....

Possibly the transistor tester.

Yes, the transistor and capacitor tester, if it can switch between RMS and average, what you can and can't do before frying it when measuring current, what are the actual SPECS and tolerances on each range.....

like I said.... I need the manual for the stuff that I need the manual for :mrgreen:
