Melting multimeter

Demonstration of what happens when cheap multimeters are used at high power points , and why a good multimeter from well brands such as fluke , gossen metrawatt must be purchased keeping safety in mind

Here is the website of the german company Gossen metrawatt

what's the cause?too much voltage?

@meade9166 It was a test to see if the multimeter withstands a surge of high current like 20A or more , which are common in industries A good multimeter like a fluke , would just have its internals fried , without any visible external damages

But this clearly shows the safety standards of cheap chinese meters

They *FAIL* big time

Imagine if you had that meter in your hand !!

@StinkyCheese9999 i bet he hardwired the fuses to get this effect, it would take a million amps to jump the gap of the protection fuses

@TheBarathbushan

This "test" means nothing.

If a multimeter does not claim to be able to withstand 20A, which it is very unlikely that one claimed to, it should not be subjected to 20A. Further, if current is unknown a meter without a fused high current range should not be used.

Further, even a cheap meter with a high current range fuse will survive exactly the same as a Fluke - it will simply blow the fuse. Buy what you need & only subject it to what it is claimed fit for.

it burnt out because to measure current it needs to be put in series with the circuit, the meter couldnt take it and blew up, voltage is different tho digital meters generally have around 20mega ohms, (20000000 ohms of resistance) so the current takes the path of least resistance and leaves the meter unharmed but a voltage reading can be found

Why did the wires rise on their own?

Wow! My Tektronix & Fluke meters have protection everywhere for this abuse. . .

You can't afford Cheap Stuff.

went from 0.0 to ... then poof

this is how the chinese discovered fireworks :)

Melting? don't u mean burning..lol.. I wonder what voltage was applied?
