Despite differential probes measuring differentially, they can be used to measure common
mode signals. In this case, the V- tip is connected to ground, and the probe continues to
measure the difference between the tips. This is a useful configuration for identifying ground
problems.
The voltages in differential systems can be described by the following diagram and equations:
