The AC71 is an automatic digital clamp multimeter with two additional unique features: AutoTect™ measurement and automatic backlight. The AutoTect™ feature automatically senses what type of measurement is being made when the test leads are placed across a measurement point. The automatic backlight turns itself on when it senses a dim viewing work area.

 

  • AutoTect™ Function – automatically selects ac volts, dc volts or resistance depending upon measurement point
  • Automatic bright blue backlight turns on when a dark environment is sensed
  • Easy one-button control
  • AC current to 600 A
  • AC volts to 750 V
  • DC volts to 1000 V
  • Resistance and Continuity Beeper
  • Data Hold
  • Conductor size 1.25 in, 32 mm, 750 MCM
  • Safety rated to CAT II 1000 V, CAT III 600 V, cCSAus listed

Included accessories:

  • Test Leads
  • Users manual
  • Carrying case
