High End Multimeters Use Reed Relays To Measure Low & High Voltages
High End Multimeters
Introduction
With the ever increasing requirements for electronics and electronic systems, the need exists to be able make voltage and current measurements covering several orders of magnitude. From nano-volts to kilovolts and from fempto-amps to amps. To do this with one instrument is almost impossible; however, multimeter designers have been able to expand the order of magnitude of these measurements in recent years. To be able to do this, the reed relay has become an essential component. MEDER’s specialized reed relays have helped designers meet this challenge.
