be present. The differential amplifier is unique in its ability to measure signals originating from sources with different
ground potentials relative to the computer

providing it is connected properly.

The most common error made in connecting differential amplifiers is the tendency to ground both ends of a signal
shield. This causes current to flow through the shield and induces noise on the signal to be measured. This problem is
eliminated by ensuring that only one ground exists on the signal circuit.
