The Model 721 combines the simplicity and
familiarity of digital clamp-on's 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 information. You can troubleshoot and measure power quality
with the ease of using a digital clamp-on - simply, safely, and
economically.
