The 610C Electrometer is a versatile, completely solid-state instrument which measures a wide range of dc voltage, current, resistance and charge. The Electrometer's input resistance of greater than 10 14 ohms is the result of extensive instrument development with high input impedance transistors. The Model 610C has all the capabilities of conventional VTVMs, but it can also make many more measurements without circuit loading.
