can be enabled: Hot+Neutral to Ground and patient leads to Ground. ES601-US can perform one of the
tests, both tests, or neither.
If Hot+Neutral to Ground is checked, ES601-US will apply a high voltage between the hot and neutral
shorted together and the ground pin at the AC line cord of the DUT that would normally be connected to
ground. ES601-US will measure the resulting current and report the test result as resistance in megohms.
If patient leads to Ground is checked, ES601-US will apply a high voltage across the patient leads and the
line cord ground pin of the DUT. ES601-US will measure the resulting current and report the test result as
resistance in megohms. The patient leads to Ground test is not provided under the IEC61010 standard.
8.6.7 Load Current (AAMI-ES1, IEC60601, VDE0751, IEC62353 and IEC61010)
Load Current is a test where ES601-US connects an internal ammeter to the DUT and measures the current
drawn from the AC line when the DUT is powered and running. This test can be enabled under the Load
Current radio group by selecting Measure, or disabled by selecting Skip.
8.6.8 Ground Resistance (AAMI-ES1, IEC60601, VDE0751, IEC62353 and IEC61010)
Ground resistance is a test where ES601-US tries to source current into the dead short circuit that should
exist from the ground pin on the line cord of the DUT to any exposed metal part on the DUT's enclosure.
ES601-US measures the resulting resistance in ohms.
8.6.9 Leakage Current (AAMI-ES1 and IEC60601)
If the Leakage Current checkbox is checked, ES601-US will perform external case leakage (AAMI) or touch
current (IEC60601) tests, and internal case leakage (AAMI) or earth leakage (IEC60601) tests. Patient leads
and lead-to-lead tests may be optionally enabled. Conditions of the AC power supply for these leakage tests
can be set under the Supply Conditions panel.
8.6.10 Leakage Current (VDE0751 and IEC62353)
If the Leakage Current checkbox is checked, ES601-US will perform a Device Leakage Current test. A
Patient Leakage Current test may be optionally enabled. Note: The AC supply conditions for each test are:
Equipment Power is On, Neutral is Normal (connected), and Ground is Normal, according to the
requirements of VDE0751.
