The WT230's advanced specifications and its wide range of functions let you handle all your measurement applications from low-frequency to high-frequency inverters using a single power meter.

Wide Frequency Range
Wide frequency Range Lets You Work on a Variety of Different Applications.

• Low-frequency Equipment
  Low-frequency measurements starting at 0.5Hz can be used for evaluations of converters and motor etc.

• Commercial Power Supplies
  Basic Power Accuracy: 0.1%

• Inverters
  100kHz power frequency range
  Now you can obtain more precise measurements on
  high-frequency equipment such as inverters.

Surge Current and Maximum Load State

• Maximum Hold Function for Voltage, Current and Power. This Function lets you keep, on the display, voltage and current peak values, voltage and current RMS values, and maximum values for active power, and reactive power.

Half-wave Rectification, Intermittent Control, Distortion Waves

• Measurement of DC Components. In addition to using DC inputs, you can obtain precise measurements of signals containing DC components, such as intermittent signals and half-wave rectification signals.

Constantly Changing Signals

• Quick Response with Display Updating as Fast as Every 0.1 Second.  
  With measurement intervals as short as 0.1 second, you can capture transient phenomena with a fine level of detail. You can also reduce the time per measurement for increased through-put in production testing. 

Noisy Signals

• Line Filter Function (fc = 500Hz)
  This function lets you measure fundamental wave rms values for inverter output voltages.

Note:
 

Instead of taking notes, you can use the internal memory to store and recall settings and field measurement data.
