WT3000 Controls are easy to use, easy to view
The WT3000 was designed with user-friendly functions and controls in response to user requests for a simpler range setting operation and more user-friendly parameter setting display process.

• Range settings using direct key input.

• Intuitive control using cursor keys.

• Using item pages to set display preferences.

• A variety of display formats.

• 50ms data; updating intervals, compensation functions.

• A variety of integration functions: User-defined function, Efficiency Calculation Function.

Direct Key Input Range Settings

The range indicator on the WT3000 is a seven-segment green LED, so the set range can be monitored at all times. The range can easily be switched using the up and down arrows.

Easy Cursor Navigation and Numerical Settings
Cursor keys can be used to move the screen cursor in four different directions, so it is easy and intuitive to set scaling factor and other settings.

Setting Display Preferences
Item pages make it easy to set data you want to view for each
 

The WT3000 has nine item pages for displaying measurement values. Once you set the measurement parameters you want displayed on a particular item page, you can easily switch between entire groups of displayed parameters. For example, the following settings make it easy to switch and compare data.

Page 1. Voltage, current, active power, and current frequency for input element 1.
Page 2. Voltage, current, active power, and current frequency for input element 2.
Page 3. Voltages for input elements 1, 2, 3 and 4.
Page 4. Currents for input elements 1, 2, 3 and 4.
Page 5. Power for input elements 1, 2, 3 and 4.

Formats for Viewing Waveforms and Numerical Values 

The WT3000 lets you display input signal waveforms in addition to numerical data. This means you don't need to connect a special waveform analyzer just to check signal waveforms.

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 10kHz can be displayed accurately.

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

Apparent Power Integration and Reactive Power Integrations
 

• Active power, current, apparent power, reactive power
  In addition to the active power integration function (WP) and current integration function (q) included in earlier models, the WT3000 also has a new apparent power integration function (WS) and reactive power integration (WQ).

• A wide effective input range for high-precision integration
  The WT3000 has a wide effective input range, from 1% to 130% of the measurement range. This enables higher-precision integration measurements on measurement subjects with current values that fluctuate widely from large currents down to faint currents in the standby state.

• Mean active power (using user-defined settings)
  Mean 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.
