The big fuses are only necessary when working with higher voltage and high current, like in industrial settings.
The small fuses can break anything at low voltages, but the meter may not have enough protection to handle the current.
Clamp meters are not precision meters, but are fine when a few percent tolerance is acceptable. They are not good at lower currents, there the precision will be even worse and it is important to zero the meter
I’m in on a UT2010e at the mentioned price range, but I prefer an option for direct pay, not through PayPal if that’s possible. Interested regardless, awaiting details.

(Edited my post and noting that PayPal is pretty universal and I’m quite sure will be usable here if you want it- I just prefer otherwise where I can)
I am interested in the Uni-T clamp meter, what do I need to do to join the group buy?
I bought my Mastech MS2108A trying to upgrade from the Velleman DMM I had that I knew was lousy with stock leads but seemed pretty close with home made 8.5” 12Ga Turnigy leads. But I was getting into higher amperage lights and knew too that the Velleman was gonna blow. I’ve read over 21A on the Mastech, thinking I might have seen 36 once but am not sure, that was on a big triple XHP-70 light if I recall correctly but chances are my memory is jerking me around again.
At any rate, I’d like to get one of these to stay on the same page with y’all, have a comparison with the the Mastech and see if we can find “the truth”.
I just ran a test on the Lucky Sun D80 BLF Special Edition, stock group buy light that I received around 10 PM on the 28th of Dec.
With a Sony VTC5 at a rested 4.20-4.21V I got these readings…
6” 20Ga loop from the negative pad, flashlight fully assembled (sans reflector and lens)…. 3.92A
6” 20Ga leads soldered to each pad of the Noctigon, directly connected to the cell… 4.99A
20.5” 12Ga loop tail reading, still same C5 cell… 4.36A
Velleman DMM with 8.5” leads, same cell… 4.04A
So I’m willing to buy this Uni-T model for verification of what I’m actually using now, and comparison to what y’all get using this clamp meter. Should prove interesting…
