sentences:  Many meters only have a resolution of 1W when reading power; the Kill-a-Watts read down to 0.1W, but this is still too coarse for measuring low standby power.Modification to read standby power has been described and discussed in detail (with oscilloscope waveforms and measurements).Essentially, the meter's shunt resistor, used to generate a voltage proportional to load current, is replaced by a much larger value, typically 100 times larger, with protective diodes.
