This is going to sound like a bit of a dumb question :oops: ... but here goes nothing: I am using an ADC-16 to log voltage, I am measuring only a few milli volts and hence the 16 bit accuracy is nice to have, but I would also like to sample at 50-100ms intervals. Whilst I appreciate there is no way ...

Ok, update for you, me, er... (ever get the feeling you're talking to yourself?) :wink: I have used another multimeter (high quality) to measure the impedance of the ADC-16. It worked! (after a fashion). The problem I have now is that the multimeter outputs 1.01V (as can be seen in the PicoLog softw...

I should have pointed out that I need to know the impedance of my ADC-16, not any old generic value.

Thanks 8)

ADC-16 Charge & Current measurements

Hi Background: I'm using and ADC-16 to measure a voltage drop across a low value resistor (0.25 ohms). This resistor is in series along the return line from a product to its battery. I use a calculated parameter to show the current, log that for around 1/2 an hour, then (using excel) integrate curre...
