About this item This line splitter is an auxiliary tool for clamp ammeters (hereinafter referred to as clamp meters). The internal structure of the line splitter separates the wires into singles through the measurement window and allows for a 10 times current to be measured. You can measure the single conductor inside the sheathed power cable accurately and conveniently without damaging the clamp meter with the sheathed power cable. Only the clamp on one of the wires can obtain an accurate current value when using the clamp meter to measure current. Dimensions: 6.3 x 2.28 x 1.34 inches.
