The WT3000 lets you display input signal waveforms in addition to numerical value data. This means you don’t need to connect a special waveform analyzer just to check signal waveforms. 1
In addition, the optional advanced calculation function lets you display vectors and bar graphs for enhanced visual presentation. The information display shows voltage range, current range, filter, and scaling value all together, making it easy to check your settings.

1 Waveforms up to approximately 10 kHz can be displayed accurately.

2 760302, 760303 and 760304 model. Requires the optional advanced calculation function (/G6)

Fast updating allows you to precisely capture rapidly changing transient states in the measurement subject.

* The WT3000 switches between two different calculation systems depending on the data updating interval. See page other for details.

The WT3000 has compensation functions for high-precision measurements. These functions can compensate for instrument-related losses resulting from the power meter’s internal impedance as well as losses related to wiring during measurement with two power meters. The following compensation functions are provided to compensate for instrument-related losses:

• Efficiency compensation: This function compensates for instrument-related losses occurring during efficiency calculation.
• Wiring compensation: This function compensates for instrument-related losses caused by wiring.

When measurements are performed using two power meters with three-phase three-wire wiring, errors may occur if current flows to the middle wire (or if there is a leakage current). The WT3000 has a function to compensate for such errors. Even when measurements are performed with two power meters (requires measurement with three-phase three-wire (3V3A) wiring), the current flowing to the middle wire is calculated, and a corresponding correction value can be added to the power measurement (requires /DT option). This improves the accuracy of power measurements.
