At that price, why not buy it? Of course the OP said "calibrate." I come from a tradition that says one can't calibrate an instrument using an uncharacterized instrument. Who knows how the manufacturer in Guang Dong Province, China, arrived at the stated accuracy of +/-(2%+3) on the 400A range---whatever that means; the terms are not defined. If I could borrow, I'd choose an instrument from someone like Fluke whose statements I have reason to trust (assuming the instrument hasn't been mistreated, as so many clamp-ons have been). Unfortunately, the Fluke i410 is priced over USD200. If I had to buy, I'd try this Uni-T device and characterize it myself before using it. Thanks for the pointer. Now that I know of it, I find the same instrument listed all over the Internet.
