Aven (MasTech) 18910 Smart SMD Tweezers Tester Review - More Gadget Tech Thoughts

So Different from to .. Which is correct

[@fritzj6803]

I experienced the same problem with the Mastech MS8911. My $19.95 handheld meter was more accurate when testing capacitors off circuit.

[@ChrisSmith-wm7lz]

Hi. Have a set of these but not sure how accurate they are. I also have the bt meter bt-4070c and not sure if these are accurate either. If I test the same smd capacitor in or out of the circuit with both testers, the readings are not even close to each other. Say for instance with one set the test could say 0.01nf and with the other set but the same capacitor I get a reading of let's say 2.1nf. It's useless with a circuit and schematic for that circuit as I don't know which one would be close.

The only way to tell which one is accurate is to remove the capacitor from the circuitboard and tested independently.

[@biggboss3946]

is it okey to test a resistor/capicitor while its connected to the circuit ? what if there is another resistor is connected with it in parallel ?

[@GadgetReviewVideos]

No, this won’t give accurate results for measuring in circuit. That’s what the packaging wants you to think, but my testing showed it wasn’t an,e to do this like some PEAK testers can.

Thank you for the video, it was good to check the out of board readings of the tweezers vs the fluke. BTW, what was the deal with the whispering? :)

[@GadgetReviewVideos]

I’m glad the video helped. As for the whispering I think this was my friend in the background talking, he was out of mic range.

How about the more expensive ones like the $200 ones? Those work better in-line?

[@GadgetReviewVideos]

+Tony Tone Hi Tony, if your talking about the Peek ones then yes. I think they are designed and made to work inline and probably part of the reason they cost more. I don't know of all the peek models work inline, or about other makes. I would be sure to check the manufactures specifications before buying any. Maybe even email their support to confirm it works inline. But the reality is most meters won't be able to focus on measuring a single part without also taking reading of other parts connected in line if they are set up in parallel or series.

Hi everybody, anyone in this planet, please help me. can this tweezers test a regular big capacitor and resistor ,i mean non smd because i plan to get cheap one for my school project .. tq

[@GadgetReviewVideos]

Yes, it probably can but not if they are part of the circuit. If it's on the PCB you won't get an accurate reading. If you need something for a school project I would suggest buying a semi cheap digital multimeter. Maybe something in the $30 to $50 range. Almost all $30 range multimeters will measure resistance with the OHM function. And some have the ability to measure capacitance. If you can find a $30 to $50 meter that has HRC fuses and does capacitance then I would say that's probably good enough for your school project. If it uses a glass fuse then it still might work, but the quality may be less then one that has slow burn HRC fuses. But if you buy the $5 one it won't be that accurate and probably won't do capacitance, the probes will be cheap that come with it also and will give inaccurate reading for resistance. For about $100 you can look at my review on the EEVBlog Brymen BM235 meter, it does a lot for the price.

[@MayurPanghaal]

Thx.Saved me my money.

[@ChrisSmith-wm7lz]

I've bought these and they are, to be honest, a pile of shit. I test a cap in scan mode and it shows up as being a diode. Sometimes it won't hold a steady reading, it flashes erratically. Supposed to read in circuit but won't give a reading. Useless piece of shit.

[@shahidkhan-mb8rm]

i buy same one but its waste of money
