A portable measurement device comprises: an elongated body with a distal end and a proximal end; a stationary portion fixedly mounted to the distal end, and a movable jaw movably mounted to the distal end and movable between a closed position and an open position, wherein in the closed position the movable jaw and the stationary portion form a closed loop with an inner diameter of less than or equal to 10 mm, wherein the closed loop can generate a sensing current, and in the open position the movable jaw and the stationary portion define a gap allowing a wire under test passing therethrough and into the loop between the movable jaw and the stationary portion; a switch for driving the movable jaw to move between the closed position and the open position; and a measurement circuit disposed within the elongated body and electrically coupled to the stationary portion and the movable jaw to receive and measure the sensing current. |
