It's all fun and games until it says the mains electric is off, and somebody actually trusts it... The whole multimeter for people who don't know how to use a multimeter is just a bad idea. The autodetecting cannot work full stop, there is no way you can tell if a battery is ok unless you know the configuration. They showed it testing LiPo batteries, how does it know how many are in series? Without sounding snobby, if you don't know enough to use a basic £10 multimeter, you probably shouldn't be playing with electricity. Had they gone for adding the Bluetooth, and graphing functions to a cheap/ basic off the shelf multimeter, it could have been successful. It's ironic how they say a normal multimeter is too bulky, when those probes are huge (I have much smaller screwdrivers!). The 121GW does look like a solid product, shame it's a little overkill for my needs.

all these multimeters with auto-off .... So one their claimed advantages is that they do not have a red and a black probe, instead they have one ring and two rings???

@haajee1 5 лет назад

I always forgot to turn my multimeter off. But after a 15 minutes and no changes in measuring it will beep and then after 1 minute turn off. It saves me battery ;)

@uwezimmermann5427 5 лет назад

@@haajee1 - the ones I own and have seen so far will switch off after a certain time (with or without previous warning) whether there are changes in the measurement readings or not.... e.e. the Aneng8008, but also other reputable brands...

I've only had cheapo meters that do not have auto off and I usually have to buy a new battery every time I go to use it because I always forget to turn it off lol

@H-77 4 года назад

I can't stand the auto-off. If it's a power amp I'm working on, I probably want to look at thermal tracking in the output stage. One meter monitors that current, and I may test it over the course of several hours with varying loads and temperatures. Automatic power-off becomes very annoying.

@Mic_Glow 5 лет назад

if you can't turn a knob you shouldn't dabble with electricity at all. Every device comes with magical book called "instruction manual" which allows someone with a bit of frontal lobe development and the rare ability to read to use it on a basic level. The manual also doesn't use "technical jargon" as stated in their ad.

@maximilianmustermann5763 5 лет назад

You know, a simple voltmeter of that form factor would be useful, but with a display on the probe. And, well, that gives accurate readings. Even if they'd cloned the voltage detection circuitry of an ultra cheap multimeter it'd be better than it already is.

Regarding the noisy display of the voltage, is it correct that just the internal 12 bit ADC of the microcontroller is used? Any analog filtering on the signal input? Any digital filtering. Wondering why the 324 quad op amp used as very noisy.

A voltage meter is a device for doing just that, telling me what voltage is any measured point of a circuit. it is not for showing absolute value (that what are true rms adc's for) if i need to know if a power rail is above or below the ground level in a circuit the meter should just tell me that, and that is what any even the cheapest multimeter do.
