Vector and Bar Graph Displays
Item
Specifications
Vector display
Displays the phase differences of the fundamental signals using vectors. This feature can only be
used on models with the harmonic measurement option.
Bar graph display
Displays a bar graph of the amplitudes of each harmonic. This feature can only be used on models
with the harmonic measurement option.
Trend Display
Displays a graph of measurement function numeric data trends.
The trends of up to eight functions can be displayed.
Data Storage
Item
Specifications
Binary save
Saves data directly to the medium* at the data update interval. The maximum file size is 1 GB.
ASCII save
Automatically or manually converts data saved in binary format to ASCII data (.csv extension) after
measurement finishes. The maximum file size is 4 GB.
Internal memory
Approximately 20 MB
Store interval

Harmonic Measurement
Item
Specifications
What is measured
All installed elements.
Method
PLL synchronization
Frequency range
The range for the fundamental frequency of the PLL source is 10 Hz to 1.2 kHz.
PLL source
• Can be set to an input element voltage or current or to an external clock signal.
• Input level
50% or more of the rated measurement range when the crest factor is 3.
100% or more of the rated measurement range when the crest factor is 6.
• The frequency filter must be turned on when the fundamental frequency is less than or equal to
440 Hz.
FFT data length
1024
FFT processing word length 32 bits
Window function
Rectangular
Anti-aliasing filter
Set using the line filter. (Set to OFF or 5.5 kHz.)
