Analysis rate Once/16 cycles
Analysis item Harmonic level: Level of each order of harmonic for voltage, current,
and power
Harmonic content: The content of each order of harmonic for voltage,
current, and power
Harmonic phase angle:
Phase angle of each order of harmonic for voltage, current, and power
Total value: Total up to the 40th order harmonics of voltage, current,
and power
Total THD: Voltage and current (THD-F or THD-R)
Measurement accuracy Harmonic level
1st to 20th orders: ± 1.0%rdg. ± 0.2%f.s.
21st to 30th orders: ± 1.0%rdg. ± 0.3%f.s.
31st to 40th orders: ± 2.0%rdg. ± 0.3%f.s.
For the current and voltage, the clamp-on-sensor specification
shall be taken into account.
Harmonic power-phase angle
The accuracy guarantee range is 1% and over of the range for
each order of the harmonic voltage (current) level.
1st to 6th orders: ± 3

The clamp-on-sensor specification shall be taken into account (k =
order of the harmonic).
Harmonic Measurement
Settings
VT (PT) ratio
0.01 to 9999.99
CT ratio
0.01 to 9999.99 (Set separately for each circuit)
Measurement start
method
Manual/time setting
Time is set as: year (4 digits)/month/day/hour: minute (24-hour clock)
Measurement stop
method
Manual/timer/time setting
Time is set as: year (4 digits)/month/day/hour: minute (24-hour clock)
The timer is set to between 1 second and 8784 hours.
Data-output interval Standard/short-term
The maximum measurement period is one year. Measurement stops
immediately after the elapse of that period.
When the memory capacity is exceeded, measurement is continued.
Performance-assured PC card: PC card 32MB,64MB (optional)
Standard interval:
1/2/5/10/15/30 seconds 1/2/5/10/15/30/60 minutes
The number of output items depends on the interval setting.
Short-term interval:
1 waveform/0.1/0.2/0.5 seconds
Only instantaneous values are output.
Data is saved in the internal buffer memory (no backup function) tem-
porarily, and is then saved in the set medium (PC card/internal mem-
ory) every 10 seconds.
Medium for saving data
Memory: PC card/internal memory
When the PC card is selected, if it is not installed, data is saved in the
internal memory.
