ES601Plus OPERATING MANUAL8.5.7 Load Current (IEC60601, AAMI-ES1, VDE0751, IEC62353 and IEC61010)Load Current is a test where ES601Plus connects an internal ammeter to the DUT and measuresthe current drawn from the AC line when the DUT is powered and running. This test can beenabled under the Load Current radio group by selecting Measure, or disabled by selecting Skip.8.5.8 Protective Earth (IEC60601, AAMI-ES1, VDE0751, IEC62353 and IEC61010)Protective Earth is a test where ES601Plus tries to source current into the dead short circuit thatshould exist from the ground pin on the line cord of the DUT to any exposed metal part on theDUT's enclosure. ES601Plus measures the resulting resistance in ohms. The test can be performedwith a 25 amp AC test current (per IEC60601 and IEC61010 Standards), but only if ES601Pluscontains the optional Protective Earth Test Module (PETM) accessory. Otherwise, the test willdefault to a 1 amp test current, or the 1 amp test current can be selected via the radio button. TheSkip option will skip the protective earth test entirely.8.5.9 Leakage Current (IEC60601 and AAMI-ES1)If the Leakage Current checkbox is checked, ES601Plus will perform Enclosure and Earth LeakageCurrent tests. Patient and Auxiliary Leakage Current tests may be optionally enabled. Conditions ofthe AC power supply for these leakage tests can be set under the Supply Conditions panel.8.5.10 Leakage Current (VDE0751 and IEC62353)If the Leakage Current checkbox is checked, ES601Plus will perform a Device Leakage Current test.A Patient Leakage Current test may be optionally enabled. Note: The AC supply conditions for eachtest are: Device Power is On, Line 2 is Normal (connected), and Ground is Normal, according tothe requirements of VDE0751.8.5.11 Leakage Current (Battery-powered devices)Under IEC601-BAT, AAMI-BAT, VDE-BAT and IEC353-BAT, which are intended for self-powered devices, the leakage current test cannot be disabled. The type of test performed is PatientLeakage Current.ES601pc Software/Chapter 8 # Page 148
