SMD LCR Smart Tweezer Knock off compard

I was wondering how much difference a set of off knock LCR smart Tweezers match up to the real ones I see them on amazon like the mastech ms8910

http://www.amazon.com/Mastech-Ms8910-Res...

Do these get the job done and test in circuit? Any help would be appreciated.

John, just out of curiosity, what are using this far to measure any of your components?

I believe that the only way to answer this is to take the "knock- off" meter and measure multiple resistors with known values. than use a "Quality" meter and measure the same resistors again. Compare the values and you got your answer. Each meter will have a certain variance and each meter might be different. Measure, compare, evaluate....

That's great idea thank you! I was wondering too if anyone had actually used the 2 I'm wanting to be able to test in circuit.

I would think that even the cheap ones are reliable within a certain tolerance. I just find the the cheap meter most certainly do not last as long as quality ones.

Thank you for accepting my answer. Good Luck.

+ Right off the top I see the one you linked to does not test L (inductance). It also doesn't test ESR or impedance like the products made by Advance Devices.

Click here for a web page a where they describe a hack/mod for the Mastech MS8910 Smart Tweezers to include voltage testing. They did a fairly good review on the product. They compared it's measurements to a Fluke multimeter on resistance and capacitance, over all it held up quite well with what it does measure. It should make a nice preliminary inspection tool, for the price. I'd own it for that purpose, especially with the voltage mod.
