Intuitive control by using cursor keys in four different directions.
To reduce setting errors, menus display settings in order of relative importance in order.

Two USB ports for peripherals are installed for direct data saving (up to 1 G byte) in USB memory at shortest intervals. The saved data can be opened in applications such as Excel.

In addition to numerical data, the WT500 can display input signal waveforms and trends (time variation of numerical data). Also bar graph display and vector display are available with the harmonic measurement (/G5) option.

Example:	η1 = PΣ/P1 x 100%
	η2 = PΣ/P2 x 100%

Two efficiency calculations can be set by selecting input elements or output elements from a list.

Only necessary items within the measured data like voltage, current, and power can be saved in USB memory in binary or CSV format (up to 1 GB).

In addition to integration functions of active power (WP), current (q), reactive power (WQ), and apparent power (WS), a new feature provides measurement of bought and sold watt hours.
Also, average active power can be calculated over an integration interval.
This feature is useful for evaluating the power consumed by intermittent-control instruments in which the power value fluctuates. Average active power is calculated by using user-defined settings.
