Data Update Interval (Update Rate)
Select from the following.
50ms, 100ms, 200ms, 500ms, 1s, 2s, 5s, 10s, 20s
The data update interval setting is displayed at the top of the screen.
Computing Method (Measurement Method)
Set the how to compute measurement values to one of the options below.
• Sync Source Period Average (Sync Source Period Average)
The sampled data in the data update interval is computed using the sync source period average method to
derive the measured values. (However, this excludes integrated power WP and integrated current q in DC
mode.)
This method requires the period of the specified sync source signal to be detected accurately. Check whether
the sync source signal frequency is being measured correctly by following the procedures in sections 3.1 and
3.4 in the User’s Manual, IM WT5000-02EN.
• Digital Filter Average (Digital Filter Average)
The sampled data is averaged by applying a digital filter to derive the measured values.
This method does not require the input signal period to be detected.
The computing method setting is displayed as SP or DF at the top of the screen.
Response Speed (Response)
If the computing method is set to digital filter average, set the response speed to one of the options below.
The lower measurement frequency limit is set as follows according to the response speed.
• Fast (≥100 Hz): 100 Hz
• Mid (≥10 Hz): 10 Hz
• Slow (≥1 Hz): 1 Hz
• VSlow (≥0.1 Hz): 0.1 Hz
The response speed setting is displayed as F, M, S, or V at the top of the screen.
