I purchased a coulomb meter recently. Basically, It is an instrument to measure static charge. The display is fixed and there is no way to take data from the instrument. So, I can't take continuous data or if I wanted to take I need to sit and manually do the job. I recently came to know about Arduino microcontroller and few suggested me that it can be used to transfer data. But before investing my time and resources, I wanted to be sure is it really possible to transfer data from a device to your laptop.
It will probably be very difficult to hack into a commercial product that isn't designed from the start to output values in some form. A better question might be "can Arduino be used to build a digital logging capacitance meter?", and the answer to that question is 'Yes' as can be seen by the example in this post ;-)
