Án margmælis með sannri RMS verður það virkilega erfiður!
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.
Eftir að hafa keyrt það nokkrum sinnum get ég aðeins beðið um hjálp á spjallinu, sem minnir mig á að það sé best að nota margmæli með sannri RMS til að prófa.
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.
Upphaflega var margmælirinn næstum keyptur, keyptur og notaður og fannst hann eins. Fyrir vikið ákvað ég að þessu sinni að fá mér fjölmæli sem getur mælt hið sanna rms gildi.
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.
Þegar litið er til innlendra vara er þessi gæði dálítið áhyggjuefni.
Eftir að hafa hugsað um það sá ég skyndilega japanskt upprunalegt vörumerki sem heitir GVDA, margmælir GD128 sem getur mælt raunverulegt gildi, í stuttu máli, miðað við fyrri þúsund og þrettán, var mér létt í einu. . .
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.
