ES601-US OPERATING MANUALMULTI GNDWIREPOINT-TO-PT Test Protocol Test ApplicationManual Testing/Chapter 5 # Page 56YES NO YES Measure resistance up to 10 times,between Kelvin Cable and "DUTCASE" lead. The OFFSET calibrationis subtracted from all measurements.For the first measurement, the KelvinCable should be connected to anequipotential (grounding) stud locatednear the DUT, and the "DUT CASE"lead connects to the DUT itself. Forsubsequent measurements, the KelvinCable may be re-attached at arbitrarylocations on the DUT to confirmcontinuity of the ground between theKelvin Cable and "DUT CASE" lead.Ground resistance test of permanently-installed equipment, followed bycontinuity test of grounded metal partson the equipment.Example: test of X-RAY equipment.YES YES YES Measure resistance between KelvinCable and the test receptacle ofES601-US, one time. After thismeasurement, the user disconnectsthe DUT line cord from ES601-USand connects the "DUT CASE" leadto the DUT.For measurement #2, 3, 4... , theresistance between the Kelvin Cableand "DUT CASE" lead is thenmeasured, with the OFFSETcalibration being subtracted to obtainthe results. The Kelvin Cable and testlead may be moved to arbitrary pointsof attachment and up to 9 additionalresistance measurements are acquired.These additional measurementsconfirm continuity of the groundbetween the Kelvin Cable and "DUTCASE" lead.Ground resistance test of cord-connected equipment, followed bycontinuity test of grounded metal partson the equipment.Example: test of a hospital bed.Only those combinations shown in the above table are permitted by ES601-US; other combinations ofsettings are inhibited.Referring back to the Sequence Control menu, other buttons provided on the menu are:
