Now you can measure voltage without test leads. Be safer, faster, more efficient. And be everywhere, testing where it used to be impossible.
Measure voltage up to 1000 V ac through the open fork, without test lead contact to live voltage. Without opening covers or removing wire nuts. On wires up to AWG 4/0 (120 mm2), carrying as much as 200 A. It will change your job. Safer. Faster. Easier.
