The WT300E Series has a basic power accuracy of ±0.15% at 50/60Hz on all measurement ranges along with a bandwidth of 0.1 to 100kHz. The influence of power factor is also claimed to be greatly reduced: at low power factor the accuracy is twice that of the previous models.
The series covers a range of input currents from 40A down to 5mA, making it equally suitable for measuring low currents in standby power testing to the high currents encountered in induction cookers.
All industry standard communication interface ports such as USB, GPIB, RS232 and Ethernet are available for the WT300E series. Yokogawa's WTViewerFreePlus software is provided with each WT300E unit. This permits displaying and saving the measurement data, numeric values, waveform display and trend graphs. IEC62301/EN50564 software for standby power measurements is also available as a free download.
