A snap of the lever secures the connection of the sensor head cables on the SU-7 amplifier. It is no longer required to strip the wire insulation. Further, the exclusive stripper (accessory) can be used to easily peel off the sensor cable outer sheath. 1 Aligning with the mark to be detected, press the `ON' button. 1 Strip the cable sheaths with the exclusive stripper. 2 Insert the wires into the holes. 3 Flip up and lock the lever. Exclusive stripper (Accessory) 2 Aligning with the background, press the `OFF' button. Caution: The outer fluorine sheath of the chemical resistant type sensor head, SH-61R, cannot be cut off with the dedicated stripper.
