Yes: Can be measured.
No: Cannot be measured.
*1 Variable k is the harmonic order and total value. The maximum order for which the harmonic data is measured is the
maximum harmonic order to be measured that is specified in the harmonic measurement (option) menu. The data is set to
[-------] (no data) for harmonic orders without data.
*2 The total value is not measured in normal measurement mode.
*3 The measured data for the frequencies of input signals that are not specified for the frequency measurement are set to
[-------] (no data).
*4 If the voltage or current mode is not RMS, the data of CfU or CfI is set to [-------] (no data).
*5 If there are no integrated values because integration is not performed, the data is set to [-------] (no data). The data is set to
[-------] (no data) also for integration time.
*6 The delta computation option (/DT) is required.
*7 The motor version (-MV) is required.
*8 The advanced computation option (/G6) or the harmonic measurement option (/G5) is required to measure the items
related to harmonics and impedance.
(Table 2/2)
Only the specialized measurement functions can be measured in voltage fluctuation and
flicker measurement and cycle-by-cycle measurement modes.For the measurement
functions that can be measured, see sections 12.1 and 13.1 in the Expansion Function
User’s Manual IM760301-51E .
