8620

8620 is a general purpose 4-wire DMM shorting plug that provides a convenient method of shorting 2-wire and 4-wire digital multimeter (DMM) inputs together. The 8620 consists of four gold-plated banana plugs mounted to a clear acrylic cube, and a gold-plated printed circuit board (PCB) assembly. This enables easy checking of DMM offsets for the purposes of instrument verification or offset cancellation during basic testing. The resistance between HI and LO pins is very low (<1mohm) due to gold-plated pin and PCB construction. However, the absolute resistances of 2- or 4-wire configurations as well as thermal voltage offsets are not specified, and metrology traceable applications are not recommended.
