Thank you very much.
Power booster sounds like a pretty good solution.
I apologize that I am a beginner of this field, if possible, could you please inform me why removing resistors of ADC Unit corrects the current output?
Since I also tried to remove several resistors in PaHub, however, the readings increased only a little bit..
大家好，
我是一个电气小白，正在使用PaHub连ADC Unit，想做一个多频道的交流电电表。
我以前用m5stack和单独的ADC unit相连，读数和买的电流计结果几乎一样。
但是使用PaHub之后，每个channel的结果都变低，大概是真实值的70-80%。
之前有英文的论坛大佬写过可以把ADC Unit的阻抗去掉，即可恢复正常值，我试了这个方法确实可以，但是这个ADC Unit就不能用做其他用了。
有没有去掉PaHub阻抗就可以修正电流值的方法呢？
还有一个非常小白的问题，虽然查过资料但是还是不太理解，在ADC Unit中的抵抗和PaHub的抵抗是如何影响最后的读数的呢？是简单的并联串联电阻分压吗？还是有其他更深层的电路原理？
期待大佬们的回答，非常感谢！！！！！
Hi there,
I am currently using m5stack and ADC Unit to measure target AC cables.
However, when I attempted to use PaHub and 2 ADC Units to create a multi-channel system, the outputs are 20-30% lower than the results of using simply one ADC unit.
Previously, there are a couple of solutions in this forum, like:
https://community.m5stack.com/topic/3040/adc-unit-major-problem?lang=ja
https://community.m5stack.com/topic/1107/solved-fire-pahub-adc-ads1100
I really appreciate it!
However, is there any solution without removing the resistors in ADC unit? Instead, is that possible to remove any resistors in PaHub to correct the outputs?
Any does anyone know the reason/principle of removing resistors?
Thank you very much and I appreciate any reply.
