Specifications
45 Hz ≤ f ≤ 1 MHz
Specifications
Depends on the PLL source
(Approximately 200 ms when the frequency of the PLL source is 45 Hz to 66 Hz.)
Specifications
Waveform display, trend display, bar graph display, vector display, waveform computation display,
and FFT display are not allowed.
Not allowed
Moving average is not allowed. Only exponential averaging is available, and the attenuation
constant is fixed to the value as defined by the IEC standard.
Depends on the PLL source
Not selectable. The LED is OFF.

For a description of the measurement functions of IEC harmonic measurement mode
and how they are determined, see section 7.11.
Measurement is not allowed for measurement functions related to the functions above
that have limitations. For a list of measurement functions that cannot be measured, see
appendices 10 and 11 in the User's Manual IM WT3001E-01EN.
