MULTI-FLEX is a simple hand-held instrument for working Live LV which measures AC Voltage and Current, and displays Voltage, Current, Power and Power Factor. The latest version also has a Continuity Test  function to verify circuit continuity and earthing. It has a wrist-strap to leave both hands free for the probes and uses a slim Rogowski coil pick up for the current measurement so that it can be used in any situation including confined spaces.
