How Does an Electric Gauge Work? The Marshall Comp II short sweep electric gauges work via deflection of the pointer from a magnetic field that is directly proportional to the signal input being measured. The magnetic field is generated by a tightly wound coil. An increase or decrease in voltage through the coil creates a corresponding change in the magnetic field, which in turn moves the pointer. Marshall SCX full sweep electric electric gauges utilize a patented high-end stepper motor movement to move the pointer to an exact position. The pointer movement is controller by a microprocessor that reads the input signal and moves the pointer accordingly. Back to FAQs
