It reports several parameters, but the only one I've found of any practical use is hFE. It's good for getting an idea of small-signal gain or finding a dud.
One thing it is not measuring well is h
FE, this is the DC bias amplification, and it only tells the ratio between Ib and Ic but ib is not adjustable or selectable. But it is good for a quick test or more or less matching transistors.
Small signal gain is h
fe and this is the change Ic caused by the change in Ib. The Peak does not give that value.
I compared mine against two curvetracers and 4 transistor testers. If i used the Data the peak gives to set the CTs, the h
FE the results are not the same, it can be from 100 % off to about ight depending on the type transistor.
Batterys are odd, mine were all empty ( got 3 peaks I got from a friend who had not used them for 2 years) and I was not amused by the bad leads, clips and odd cabinet.
So i builded them in a mains powered cabinet using good connecors and an ectra transistor test socket.
Do not trust it 100 %, i have seen strange hings, like thinking a transistor was a FET, thinking a pnp was a npn ect but 95% of the time it is right and a handy tool.
The ESR60 is rather good over 0.1 Ohm, under this it loses some accuracy. ESR performance degrades under 10 uF. C measurenent is most times 5-10 % off but that is no poblem.
The LCR meter is nice if you have not a better one and to quickly test some components f.i. While sorting, or cleaning up the junkbox. It is not very accurate and i do not like the fact you have to wait before it starts to measure or press the button again. I rather like a meter that keeps reading as long as the DUT is connected and until I switch it off.
If you look what is inside and the performnce I think they are a bit over priced.
