Accurately Measuring Nanoamperes Application Note: Using the Tektronix DMM4020 Multimeter
■Standby current leakage is often designed into a device. It is a side-effect of products providing :instant-on: capability, consumer electronics with always-on clock displays, as well as power conversion devices such as battery chargers. Because energy is power multiplied by time, even if the standby power level is low, a significant amount of energy can be consumed over long time periods, dissipating AC line power and draining power stored in batteries.
■Accurately measuring low-level leakage currents in the nanoampere range is a challenge for most digital multimeters. The Tektronix DMM4020 multimeter offers a dedicated circuit for measuring leakage currents with a resolution of 1 nA to meet this challenge.
