摘要： A test lead assembly includes a first test lead having a first cable extending between a distal end and a proximal end, a first test probe attached to the distal end and a first plug attached to the proximal end; a second test lead having a second cable extending between a distal end and a proximal end, a second test probe attached to the distal end, and a second plug attached to the proximal end; and a fastener member for repeatedly releasably engaging at least a portion of the first cable with at least a portion of the second cable along a length of the first and second cables. The test lead assembly and a measurement device incorporating the test lead assembly can avoid or at least reduce knotting of the test leads.

摘要： An electronic measuring device includes a main printed circuit assembly and one or a plurality of channel modules. At least one channel module includes a channel printed circuit board and a first insulating housing that defines a cavity covering at least part of electrical elements mounted on the channel printed circuit board. A first conductive shielding frame is at least partially disposed on the first insulating housing and separated from the channel printed circuit board via the first insulating housing. The first conductive shielding frame covers the at least part of the electrical elements mounted on the channel printed circuit board. A second insulating housing on the first conductive shielding frame is configured to sandwich the first conductive shielding frame between the second insulating housing and the first insulating housing so as to lengthen an electrical path from the first conductive shielding frame to the channel printed circuit board.

摘要： A clamp meter includes a meter body and a clamp jaw assembly mounted to the meter body. The clamp jaw assembly includes a first clamp jaw and a second clamp jaw which are movable in relation to each other between a closed position and an open position. In the closed position, distal ends of the first and second clamp jaws meet to define an enclosed area between the first and second clamp jaws, and in the open position, the distal ends of the first and second clamp jaws are separate from each other to define a gap allowing a wire under test to pass therethrough. The clamp meter further includes a locking member mounted within the meter body. The locking member is operable to releasably lock the first and second clamp jaws in the closed position.

The clamp jaw assembly includes a first clamp jaw and a second clamp jaw that are movable in relation to each other between a closed position and an open position. In the closed position, distal ends of the first and second clamp jaws meet to define an enclosed area between the first and second clamp jaws, and in the open position, the distal ends of the first and second clamp jaws separate from each other to define a gap allowing a wire under test to pass therethrough. The clamp meter further includes a locking slider positioned within a slot inside the meter body. A switch assembly moves the locking slider longitudinally within the slot between locked and unlocked positions. In the locked position, the locking slider blocks the first clamp jaw from movement.
