The Probe Unit was just a testing tool to see what kind of results I could get. My original plan might still work but it will take some effort to apply the calibration information (which could be done after the Nano Logger collects all the raw data).
Voltage Probes. These are usually used to measure high speed, signals up to 12 Volts. These are best used to make measurements on circuit elements that have a high frequency which require the least probe loading. A probe with lower input capacity can allow higher input impedance at high frequency.
