The output resolution for the WT3000 is 16-bits.

When the selected data update cycle of the fundamental wave is shorter than the width of the analysis window determined by the fundamental frequency (cycle of the fundamental wave), measurement is not performed and no ...

Selecting formulas for calculating apparent power and reactive powerThere are several types of power—active power, reactive power, and apparent power. Generally, the following equations are satisfied:Active power P = ...

The waveform may actually not be a pure sine wave. Even though a 50/60 Hz sine wave is expected, the following factors may be involved: The waveform is slightly distorted (harmonic components are mixed in) Small ...

• Check the "Sync Source" and zero cross filter (frequency filter) settings.
• For the WT3000, "Sync Source" setting is irrelevant if the data update rate is 250 ms, 500 ms, 1 s, or 2 s.

Check for differences in the specifications or features of the instruments. For values that do not match when inputting a 50/60 sine wave Check whether the value is within the specifications (error) of each power ...

The measurement intervals of the measured I/O data must overlap exactly. Check the sync source setting. For example, route the input to a three-phase device under measurement to input elements 1-3 on the power meter, ...

• In the case of three-wire, or 3V3A wiring, or three phase power source, they do not match because it is the line to line voltage that is measured

In the three-phase three-wire, or 3V3A wiring scheme, the phase angle of voltage between each input element is 60 degrees because it is the line to line voltage that is measured. Please download and refer to the ...

In the three-phase three-wire, or 3V3A wiring scheme, the phase angle of voltage and current input to each input differs from that of the actual load because it is the line to line voltage that is measured.  In ...

When measuring input signals of distorted waves, signals that are DC-offset or signals that include superimposed harmonic components, will result in different values for power factor and phase angle than those expected ...

The peak value and crest factor may be unstable if they have not been captured accurately. If the peak value is not stable, neither will the crest factor be stable. The cause is the difficulty in capturing the narrow ...

The difference in measurement values can be attributed to the difference in calculation methods for normal mode and harmonic mode.   The voltage, current, and power in normal mode are displayed as the total of the ...

The following may be causing the problem. 5V may have occurred during rating. Check the range setting again. DA output error can affect the values when the input is smaller than the rating. Have you checked the error ...

Check the Synch Source and Frequency Filter settings When a single-phase signal being measured fluctuates around power factor of 1.Slight fluctuations in the measured values of voltage, current, and power can cause a ...
