| janengelbrecht:
I have built an incircuit ESR meter based on arduino. My only problem is calibrating it. I only have the AVR component tester from ebay TC-7. And we all know it isnt really that good. Is there some industry standard methods to measure ESR with an oscilloscope, tonegenerator and perhaps a few components ? |
| xtech:
Use resistor, then measure unknown capacitor and check if adding same resistor in series with capacitor changes reading by proper value. |

I would use a simple small value like 1Ω resistor, it would be more than close to the real result, and enough to test if a capacitor is good or not. I also have resistors to 50mΩ to check my esr meters ... |
