I was recently given this DMM. I'm sure that it won't be up to Fluke standards Biggrin 

Don't worry, it's not going anywhere near mains.

Also in the batch of kit was Tenma clamp meter. Are Tenma any good?
What a wonderful rip-off!
Tenma kit is generally OK, and their clamp meters are pretty solid.

We bought a batch of Tenma meters from Farnell a while back - perhaps 15 or so years. They all failed within a couple of years with just light use. Failure modes were various, but the "best" was a frozen display that simply stopped updating, which meant you could think that a live circuit was dead at 0.000V.

Inside, they were made by UNI-T. The standard of construction was pretty horrible.

I've mentioned this experience a few times before, including on my website (https://www.markhennessy.co.uk/budget_mu..._ut61e.htm), so apologies for the repetition, and of course, they won't all be bad, so I'm very aware that I'm generalising. What you have might or not be made by UNI-T, and not everything from UNI-T makes is bad. The UT210E clamp meter gets good reviews, including one from me. That uses the modern chip that revolutionised the cheap multimeter scene, and seems pretty good within its limits (watch for the AC bandwidth though). So what you have might be fine. Take one apart to figure out the details...
Are the Tenma power supplies such as these OK?
