A
(9) Peak measurement function
It is possible to measure peak values of a voltage or current waveform.
Also, using the peak hold function, motor surge current peak values, and the
peak values of effective values can be measured.
(10) Separate integration values for each polarity
For current and active power, positive, negative, and total integrated values
are provided.
Each channel can be integrated separately.
(11) Three averaging functions
Time average, sliding average, or exponential average can be selected as the
averaging mode.
(12) Three-channel frequency measurement function
The unit has a three-channel frequency measurement function, allowing
separate frequency measurement when multiple systems are being tested.
(13) Analog signal input from an external device (using optional 9603
EXTERNAL SIGNAL INPUT UNIT
)
It is possible to input a separate analog output (or pulse signal) from the
system undergoing power measurement, for easy on-screen conversion.
For example, inputting the analog outputs from a torque meter or rotation
counter enables the converted torque or rotation values to be shown on the
screen. The power can also be computed from the torque or rotation values.
(14) Harmonic analysis/flicker measurement function (option)
The harmonic analysis function can analyze up to the 50th harmonic of the
voltage, current, or active power waveform, for fundamental frequencies
from 5 Hz to 440 Hz.
(15) High visibility color LCD
The color LCD screen has a wide viewing angle, and allows simultaneous
display of different information without requiring screen switching, giving an
at-a-glance grasp of the overall state of the measured system. In combination
with the optional harmonic analysis/flicker function, it is possible to use
different colors to distinguish harmonic analysis graphs and waveforms.
