بدون مقياس متعدد مع RMS حقيقي ، سيكون الأمر مزعجًا حقًا!
In fact, I didn't care about this at first, but recently I went to a company to check the power supply, and I did not find any problems with the old watch at hand, but the other party's fuse broke every three days, which made me very annoyed, absolutely There is a problem, but I just can't find out what is causing it.
بعد تشغيله عدة مرات ، لا يمكنني طلب المساعدة إلا في المنتدى ، مما يذكرني أنه من الأفضل استخدام مقياس متعدد مع RMS حقيقي للاختبار.
Thinking about it, it is indeed possible. I borrowed a colleague's multimeter and went there. I didn't expect that the current measured was much higher than the previous ones. I also accepted it.
في الأصل ، تم شراء جهاز القياس المتعدد وشرائه واستخدامه تقريبًا ، وشعر بنفس الشيء. نتيجة لذلك ، قررت هذه المرة الحصول على مقياس متعدد يمكنه قياس قيمة جذر متوسط التربيع الحقيقية.
I originally wanted to buy and borrow the kind, but when I saw it on Taobao, I was instantly scared off by the price. It has to cost more than 1,300... Although the American products are of good quality and I know that safety is important and life is important, the price really makes me a little bit overwhelmed. It's good to see some big European and American brands, but four or five hundred can only buy average watches.
بالانتقال إلى النظر في المنتجات المحلية ، فإن هذه الجودة مقلقة بعض الشيء.
بعد التفكير في الأمر ، رأيت فجأة علامة تجارية يابانية أصلية تسمى GVDA ، وهي GD128 متعددة المقاييس يمكنها قياس القيمة الفعالة الحقيقية ، باختصار ، مقارنة بالألف والثالثة عشر السابقة ، شعرت بالارتياح في الحال. . .
I've been using it for a while now, and it feels pretty good. The quality is very good, so far it seems to be a good value for money.
