1.2 Features
A multi-function microcomputer
The built-in microcomputer offers various functions
in a compact form.
Display of true rms values
The true rms value conversion circuit allows
accurate measurement of currents with distorted
waveforms.
Enables power measurement
When both current and voltage are input
simultaneously, the power factor, phase angle,
reactive factor, as well as power can be measured,
and phase detected.
Enables harmonic measurement
Higher harmonics of current and voltage up to the
20th order can be measured. Moreover, overall
harmonic distortion factors and content can be
displayed.
DATA OUTPUT function
Data can be output when the unit is directly
connected to a printer. This function requires the
optional 9442 printer (DPU-414, Seiko Instrument
Inc.) and 9636 RS-232C cable.
