Description

The Harmonic Meter Model 721 combines the simplicity and familiarity
of digital clamp-ons with today's critical information on power quality and
harmonics.
Operation is simple and direct, with no menus, calculations or complex
analyzer procedures. Select Amps or Volts on the rotary dial, connect, and
measure. The push of a button gives additional or more specific informa-
tion. You can troubleshoot and measure power quality with the ease of
using a digital clamp-on — simply, safely, and economically.
The Model 721 performs current and voltage measurements in True RMS,
and provides immediate readings of total harmonic distortion (%THD), dis-
tortion factor (%DF), crest factor (CF) and Peak of distorted currents and
complex voltages. It also gives the minimum, maximum, maximum Peak
and average measurement values so you can record for over 24 hours to
monitor daily fluctuations. And, you can measure frequency (Hz) through
either the current or the voltage at any time.
In addition, the instrument's analog output allows display of the current
waveforms on any oscilloscope or hand-held scope while measuring; or
the output may be used for loggers and recorders.
The Model 721 incorporates True RMS electronics and measurement
techniques to ensure correct and accurate readings on distorted wave-
forms. Use the Model 721 as a comprehensive tool for troubleshooting
as well as for daily measurements on circuits supplying traditional and
today's nonlinear loads.
Beyond the absolute product ruggedness and overall design qualities
—the Model 721 is built with GE Lexan and meets specific physical
®
standards — the instrument features a high level of safety. The Model 721
meets IEC 1010-1 Category III for 600 V ratings.
