Measure voltage with or without test leads
Be safer: measure voltage to 600V through the open fork, without test leads
Be faster: not need to open covers or remove wire nuts - simultaneously measure voltage and current
Be everywhere: 17.8 mm open fork is widest in the industry; measure up to 200 A on 4/0 wires (120 mm2).
FieldSense technology for ac voltage, current and frequency measurement without making electrical contact to live voltage
