Abstract (en)
[origin: WO9904277A1] A dual conductor wrist strap monitoring circuit that allows the operator to remain at approximately zero volts. The monitor couples the operator, through resistors, to two voltage potentials equal in value with respect to earth ground, but opposite in polarity. Because typically there is symmetry in the resistance in each side of a dual conductor wrist strap, the operator is at zero potential with respect to earth ground. There is still a conductive path for the operator to discharge any charge potential they build up with no negative affect on decay times.
