原廠英文說明
The WT310 is a single phase, portable unit, with the capability of measuring low currents from 50 micro-Amps up to 20 Amps RMS and a voltage ranges from 15 to 600 Volts RMS. The WT310 was designed to accurately measure conversion circuits that use energy saving switching techniques that can cause distorted voltage or current waveforms with high harmonic content. A high resolution sixteen bit Analog to Digital converter, a digitizing rate of 100 kS/s and a bandwidth from DC and 0.5 Hz to 100 kHz allow the WT310 to perform these complicated measurements with ease.
