A part of the review has been auto-translated.
The measuring circuit is completely isolated (with optocouplers and DC-DC 5v Isolated) from the other circuits: processor, USB, charging. Does not charge from the communication USB-B. It has 2 18650 batteries (Much autonomy) Indicates the level of charge on the screen. It does not indicate whether it is charging or powered from the outside, although it has a red light behind. The display looks spectacular: viewing angles, backlight and contrast (black good) I do not think about its operation because there are already reviews on the internet that give a lot of information.
Purchase this multimeter took a couple of weeks to arrive, responsible quality in the meter itself given the price range, I didn't think much of the supplied leads and alligator clips so I replaced them with a set of UNI-T leads and screw on clips, my particular meter reads the leads @ 0.07ohms so remember to subtract the error when measuring low resistances, I also set up a simple LM317 100mA constant current source and used the 5 volt range to measure voltage across resistances and was happy with the readings matching resistance values. with rechargeable batteries certainly happy to have it on my bench and nice bright display and much easier to read with my older eyes.
Fast delivery (16.06.2022 - CZ > HU) Above: Owon XDM1241 (V3.3.1) Middle: Owon XDM1041 (V2.0.0) Bottom: Siglent SDM3065X Handheld Precision Digital Voltage Source - PDVS2mini 20bit - (THX Ian!) Better visibility from the side, from below than the XDM1041. Better calibration.
Fastest delivery ever (10 days from order) to South Africa. Well done Banggood. Product in good condition and works as specified
Nice meter, small and functional. As far as parameters are concerned, there's enough for even a "professional", fast delivery Recommend
The best desktop multimeter at this table! Beautiful women, beautiful women, beautiful women, 100%++ The best desktop multimeter at this price! Beautiful beautiful display,very accurate measurement,thank you very much,100%++++
Quality instrument with Li ion batery, works good, very well package. Thanks, Danilo
All OK.Thanks.
The product needs to be tested, but it has no mV scale.
Banggood отработал безупречно, однако задержали на целый месяц в сортировочном центре РФ, по понятным логистическим причинам. Получился подарок себе на Новый год. Упакован надежно, механических повреждений на упаковке не заметил. Проверил сравнительную точность по Keysight 34470A. Остался доволен результатами. Компактный, точный приборчик, да еще и с аккумуляторным питанием интефейсом VISA. Мечта для домашней лаборатории! Единственное, что мне не хватило в XDS1241, 4-х проводной схемы измерения R, но я не нашел за эти деньги прибора с этой функцией. И несколько удивило, что при наличии коннектора USB-C для заряда аккумулятора, интерфейс VISA подключается через стандартный USB-B. Я понимаю, почему так сделали, однако, учитывая габариты прибора, я бы остановил свой выбор на mini-USB или USB-C еще в базе XDM1041. Установил ПО на Win7-x64 без проблем, на Win10 еще не пробовал. Драйвер пришлось поставить с сайта OWON, т.к. в стандартном этот PIV&PID отсутствовал. В целом я доволен покупкой, учитывая скидку, считаю покупку выгодной. Спасибо Banggood!
