请帮忙修改下语法错误I looked schematic,and try adding 10VDC at J1& J2,we can test waveform by active magnetic and output voltage on Pin2 of U1,and so do we just test 2 items?Please advice.

I looked at the schematic,and tried to add 10VDC at J1& J2,we can test the waveform using the active magnetic method and the output voltage on Pin2 of U1,and so you just need us to test these 2 items?...
