Appendix 10 Measurement Modes and Functional
Limitations
The following measurement modes can be used on models with the advanced
computation (/G6), voltage fluctuation and flicker measurement (/FL), or cycle-by-cycle
measurement (/CC) option.The functions that can be used in each measurement mode
are as follows:
Display
Auto range
Averaging
Data update rate
Voltage/Current mode
Peak measurement
User-defined function
MAX hold
Efficiency computation
Compensation
Integration
Store
File save
Zero-level compensation
NULL
Synchronized measurement

Yes: Can be used.
Limit: Limitation on some functions.
No: Cannot be used.
*1 The rms values of voltage and current are total values, not the normal measurement values.
*2 Can be monitored using the IEC harmonic measurement software.
*3 The attenuation constant cannot be selected.
*4 Fixed to 2 s.
*5 The efficiency compensation and the compensation for the two-wattmeter method are invalid.
*6 “Integ Sync” cannot be selected, because there is no integration function.Waveform data is set to NAN (no data) if Wave Trace is selected,
because there is no waveform data.
*7 Save FFT waveforms using “Acquisition,” not “Wave.”
*8 If an item that is not measured or computed in the respective measurement mode, NAN data is saved.
*9 The settings can be changed and the function can be executed only when the measurement status is reset.
*10 Requires the motor version (-MV).
*11 Requires the built-in printer option.If an item that is not measured or computed in the respective measurement mode, NAN data is printed.
*12 Only the screen image can be printed.The list cannot be printed.
*13 Integration synchronization (Synchronize) cannot be set.It is fixed to timer.
*14 Requires the D/A output option.
*15 Requires the delta computation option.
*16 Requires the Ethernet communication option.
