Abstract :
This is a history of commercial instruments that measure impedance from the 1930s to the present day. It concentrates on general-purpose and production-test bridges and meters that measure resistance, capacitance and inductance at low frequencies. It intends to show how electronics has changed these electrical measurements just as it changed all other technologies.
