Be safer: Measure voltage to 1000 V ac through the open fork, without test leads
Be faster: No need to open covers or remove wire nuts
Be more efficient: 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 (120mm2)
Go beyond simple detection: Actually measure ac voltage and current values without test leads
