    Thank you for the high voltage safety test!
    I think the slightly worse result of the 219 is due to the larger surface of the casing. If you hold them in your hand the contact area will depend on the size of your hsnd.

      I think it was a very hard test for a multimeter who ask just 25 dollars, port included. A perfect test would have to explode it with high current surge, but I don't like destructive tests. Thanks for commenting, glad if you like it.

    Отличный тест! Особенно понравилось испытание на электробезопасность. Как мне кажется, если заменить штатные пробники на силиконовые, результат будет еще лучше. Хотя и так до опасных 50 миллиампер не доходит. Спасибо!

      glad you like it. The reading on the multimeter are in microamp. That's far from a millamp. This test was very hard, because in alternative current, and 4000V. Yes those multimeters deserve better cords. Thanks for commenting and appreciating.

      ​@@AIexanderHartdegen Спасибо за ответ. Я заказал на AliExpress RM219. Но хочу добавить одно замечание - на странице официального продавца есть ПРЕДУПРЕЖДЕНИЕ: "При измерении тока нельзя превышать 36 вольт на постоянном токе и 25 вольт на переменном токе" (многие пользователи уже сожгли свои мультиметры измеряя ток при напряжении 220 вольт). Это пожалуй главный недостаток RM219.

      @@pavlik2222 this is a kind of pure bullshit coming from manufacturer. Firstly measuring current have nothing to care with voltage source, because current measure works generaly with less than 1 volt process. BUT this caveat comes from the engineering of the multimeter, wich is not the same than a fluke. On a fluke, if you have a burned fuse, you will have nothing displayed on your multimeter, because fuse is placed mainly on the measuring loop circuitry. But on those multimeters, fuses are not on the entry but on the center of the loop measurement, and point of measurement are taken uptream fuse point. So, if fuse is broken on a Richmeter or Aneng multimeter, you will see a strange value on the display, wich can be confused by a real measurement. So in this case, if fuse is broken, the short circuit on the richmeter (or aneng) will disapear, and you will found the voltage source across the mesasuring point on the multimeter. Those measuring points are drived by very low voltage system, converting microvolt, or millivolt into amp reading. Despites a load on the circuit, you inject so an equivalent to a certain voltage (according to the voltage source) into a equivalent of a millivolt or microvolt caliber, wich can be very dangerous for the multimeter. If cares are taken properly, there is no reason to see this fact happen. But all comes from the different engineering of cheap and expensive multimeter. You can measure current on any voltage you want, if you take care to not burn the fuse. If you care, of course, you will respect the caveat of the manufacturer.

      @@AIexanderHartdegen Спасибо. Согласен, что остающееся высокое напряжение (после обрыва плавкого предохранителя) на низковольтной измерительной цепи - не лучшее решение. Хватит небольшой утечки тока на печатной плате. У одного пользователя RM219 сгорел (на пределе 20А) при проверке тока светодиодов на светодиодной лампе 220 вольт включенной в электросеть - напряжение на конденсаторе там 300 вольт, еще и индуктивность могла дать импульс напряжения куда более 300 вольт.

    Thank´s for this video, i just buy the Aneng 8008 (zt109 v0.5).. in this moment i´m capacitors update (rail volt). Next i go buy B-side 302 too. i use to be uni-T fan (low price vs quality, in field). But now (work inside) I'm impressed with Zoyi/zotek DMM´s (low price vs data adquirement).

    Very good review. I already have B-side ZT301 meter. And now I'm thinking of getting ZT303 (same as of RM303) instead because it's more accurate, has more counts and I just like that 19999 display look more. And regarding a speed of the meters I guess it can be increased by choosing a manual range instead of autoranging.

      @@AIexanderHartdegen I was looking up the RM219 on Aliexpress but one thing put me off. In the warnings paragraph It says do not input voltage on resistance mode or diode mode. This is a common mistake while working and if it cannot take mains voltage in these modes it means there is no protection and the meter will be destroyed. I was just wondering if you ever took a look at the videos posted by Joe Smith. He is very keen in testing Digital multi meters.

      @@supersilve Hello Silvio. This thing happened to me, but not with main voltage. So, the multimeter wasn't destroyed. In the 80, a DMM cost the equivalent of 500 dollars of today. And at this time, it an error was made, the multimeter was also destroyied. I use my RM219 always on low voltage application. In case I make a wrong connexion, I will not feel deeply bad, because of low cost of this product. Actualy and in my sens, you need to be very cautious when working on the main. Connecting a diode mode or ohm mode on the main is not evident, even on a Fluke multimeter. In the past, I destroyied expensive multimeter in ohm caliber when connecting it on a 48vdc. Actualy, I should be able to make this test but.. As I say sometimes, I hate killing multimeter. In a doubt I choose to be sefety. But you're right, a nice multimeter should bare all those mistake. But I think that they are nice despite all. I know Joe Smith, he is a nice guy even if he's sometimes rude in his comments. He make a test of cheap aneng. I think he should make a test on those multimeters, because he's not afraid to kill them. But I think this guy is the worst nighmare for multimeters... He is able to make those test, I think I am not. But... Normaly, all multimeters are recommended to not use them on voltage when placed on the wrong caliber :) This is very comon and not only specific to a cheap brand.

      @@AIexanderHartdegen Yes you are very right in your explanations. I work mostly on commercial amplifiers using smps. Fixing these at times you may put your probe on the wrong trace :) but I am also cautious at all times. It never happend to me till now and I am also using a cheap meter such as a VC97 or most preferably my analog tester as this is the best I find especially checking faulty transistors. A quick glance at the needle will not make me read any digits. If anything goes wrong and I blow the meter it does not cost much. I have a UT61E when I need a precise voltage measurement especially in the environment of an smps as noise generated may give a false reading.

      O RM219 tem leitura direta de temperatura com uma sonda de temperatura e é um pouco maior e mais pesado que o 303.
      O 303 é menor e mais leve, mas não possui sonda de temperatura e leitura em graus Celsius ou Farenheit. Mas é mais leve e menos volumoso.
      Em termos de funcionalidade, o RM219 é ainda mais eficiente, por conta de sua leitura direta de graus.
