hi members, I just completed a esr meter project. the title as it appears on the internet is CAPACITOR ESR METER WITH TONE. the problem is the meter does not deflect. the 100khz osc is running. the signal gets as far as U2A pin 1. the signal at pin 1 varies between 2&3 vpp. its jumping up and down. that's where every thing stops. plz help. d3 and c6 are good.
