700A True RMS Clamp DMM

Choose AC only or AC/DC Model, both with advanced functions

Features:

• True RMS for both AC Voltage and Current

measurements on traditional and non-linear loads

• Measure Line Frequency to 9999Hz via jaws —

ideal for adjustable speed motor drives

• 4000 Count display with fast response analog bargraph —

bargraph displays current while reading frequency

• Jaw opens to 2” (51mm) to accomodate

500MCM conductors• Manual or Auto ranging, Data hold

• Safety handguard design meets IEC1010

Additional features of Model 380935:

• DC Current to 700A with auto zero adjust

• Minimum, Maximum and Average Memories

• Soft Mode displays three second running average

and provides stable digital readings when load

currents are fluctuating

• Auto-Off with Manual Override• Crest Mode displays up to 999.9A peak value of current,

indicating presence of harmonics waveforms
