How to diy a Digital voltage and current meter tester -Simultaneous detection of voltage and current

In this video I will show you how to DIY a DC voltage and current meter tester,It can simultaneously detect the voltage and current of the load and display it.
Compared with a multimeter, it is more convenient.
In the video, I have the circuit for everyone.

With power supply it can measure from 0-30v or if you have another model, it can measure from 0-100v. There are two types. Without power supplz it measure from 4-30v or from 4-100v based on type you have.

這可以直接 拿來測試 機車的 電流嗎?

Hello are you sure both schematics are identical? I say no. Which one did you use finally? Thanks and all the best, Boris🇨🇭

Hello, I am sure that the two circuit schematics are the same

請問獨立供電為什麼要用9V ? 低於9V可以嗎？ 謝謝

[@apourmaker6055]

可以低於9V，這類數字表的供電一般4-28V，我建議供電範圍5-12V
