WebDec 31, 2013 · If a particular meter read full-scale with 100uA, and dropped 0.01 volts with that much current, one could use it directly as an ammeter for reading currents up to 100uA, or as a voltmeter for voltages up to 0.01 volts, but many real-world applications require reading higher currents or voltages. WebSo, they have taken the numbers on the amps scale, squared them and multiplied them by 50, to produce a matching kW scale. If you look - 10A would be 10x10x50 =5kW, so they have put "5" on the kW range above the "10" on the ampere range. But all this meter is reading is amperes - it is then deriving and displaying the equivalent kW, assuming ...
