Wide Frequency Range

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

  • Low-frequency Equipment
  • Low-frequency measurements starting at 0.5 Hz can be used for evaluations of cycloconverters and when a motor are started.
  • Commercial Power Supplies
  • Basic Power Accuracy: 0.1%
    Power accuracy is even better than in fomer WT200/WT130 series.
  • Inverters
  • 100 kHz power frequency range
    Now you can obtain more precise measurements on high-frequency equipment such as inverters.

Accuracy Is Assured Between 1% and 130%

Tm Wt210 05

Capture a Variety of Signal Types


Surge Current and Maximum Load State
MAX Hold Function for Voltage, Current, and Power *3
This function lets you keep, on the display, voltage and current peak values, voltage and current rms values, and maximum values for active power, apparent 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.


Tm Wt210 06

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 = 500 Hz)
This function lets you measure fundamental wave rms values for inverter output voltages.


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

Powerful Tools for Energy Measurement

Extended Energy Measurement Applications
Maximum Integration Time: 10,000 hours3
Time can be set between 1 second and 10,000 hours (416 days) in 1-second increments.


Battery Equipment Applications
Integrating Power Measurement by Polarity
Power and current values can be integrated separately for positive and negative polarities. Integrated values are shown with the decimal point moving according to the integrated value.

Intermittent Control Equipment Applications
Average active power display³
The power of intermittent control equipment changes significantly over time. The average active power in intermittent operations can be displayed, which is highly effective for consumed-power measurements.

One Unit Handles Standby Low-power Measurements (WT210 only)


Wide Range of 5 mA to 20 A
Tm Wt210 10The built-in 5 mA range lets you measure currents as low as 25 µA. This makes it possible to measure very low currents on such things as intermittent control equipment. The wide current range (5 mA to 20 A) means a single power meter can be used for applications such as Energy Star® measurements, to measure everything from standby-power to rated-power.


Benefit of Assured Accuracy from 1% of Rng

Justin Hampton, Nordyne, LLC

We use the WT210 exclusively for single-phase inline measurements and we have found them to be solid and dependable.

However; the WT230 3-phase meter has been a lifesaver. The selectable wiring scheme is indispensable for us as most of our 3-phase equipment uses the 3-phase 3-wire scheme. This has eliminated the confusion that lead to errors in testing from the 3-phase 4-wire meters we had previously used. As far as I’m aware Yokogawa is the only company offering this option in an inline meter capable of carrying a 30A load.
