This seems to be getting cheaper all the time, looks a good model for the cash. No codes or anything needed and delivery is freeeeee
It can be used to measure AC/DC voltage, AC/DC current, resistance, capacitance, diode, continuity testing, frequency, etc. This battery powered product uses double-integral style A/D transform as its core, and is characterized by stable function and high reliability. With the features of overload protection and backlight lighted LCD display for clear reading, this product is a perfect tool for lab, factory, radio fans, and family use.
Features: LCD display with backlight. Max. display: 6000 Counts. Automatic polarity identification. Measurement mode: Double-intergral style A/D transform. Measure AC/DC voltage, AC/DC current, resistance, capacitance, diode, continuity testing, frequency, etc. RM102 is specially designed with temperature measurement function. Over range indication: OL. Low voltage indication. Auto power off. Sample rate: 3 times per second.

Enough scaremongering here to chase away the amateurs. I'm sure most people about to click buy on the deal are having 2nd & 3rd thoughts now

Im more than happy for people to experiment with mains electric using cheap meters. if those people are happy to put their life in their hands for less than a tenner then so be it - shame they might not be around to tell us when it all goes wrong like :popcorn: {the world is overpopulated as it is}

I bought a cheap multimeter online to check my car battery, but for any AC work (and then only if I was suitably qualified) I think I would be wanting something costing a little more than £8.46

"This battery powered product uses double-integral style A/D transform as its core," - just like all digital multimeters since 1963. :fearful:
Should be OK unless you're a clot and try to measure voltage on the amps range. Proper multimeters contain a fuse which will safely handle that; this meter will just vapourise. :grin:

I can vouch for the fact that even a proper fluke will turn to a molten mess when you do that at 1000v :joy:

Ugh! But at least it will beep furiously at you if you plug the probe into the 10A socket and select volts.

I prefer 4 terminal multimeters, as it strikes me as rather too easy to flick the knob to the amp range after you've hooked it up, especially if you'd last turned it off using the OFF setting on the right hand side. :smile:
I think this is probably a rebadged zotek 101, in which case it does have a couple of fuses, unfortunately they are tiny ones with not enough separation between the terminals for a respectable amount of voltage.

Yes, I agree, and also that the switch has to handle significant current rather than just being a signalling device, which means it has to be made to a certain standard.
The trouble with the fuses isn't so much their separation but their rupture current - they have to absorb a large amount of energy if you connect the thing across a low impedance supply. Small fuses will just explode.

Yep !
