ES601Plus OPERATING MANUAL
8.5.3 Limits (All Standards)
The limits of each test can be set to the values specified by the Standard, or user-defined limits may
be selected using the Safety Limits Editor.
8.5.4 Equipment Class (IEC60601, AAMI-ES-1, VDE0751 and IEC62353)
A Class I device has a protective earth conductor (AC supply has 3 wires). A Class II device does
not have a protective earth conductor (AC supply has 2 wires). The equipment class may be selected
by radio buttons.
8.5.5 Line Voltage (IEC60601, AAMI-ES1, VDE0751, IEC62353 and IEC61010)
Line Voltage is a test where ES601Plus connects an internal voltmeter to the AC line input and
reports the AC RMS voltages seen from Line 1 to Line 2 ("hot" to "neutral" in North America),
from Line 1 to protective earth ("hot" to "ground"), and from Line 2 to protective earth ("neutral"
to "ground"). This test can be enabled under the Line Voltage radio group by selecting Measure, or
disabled by selecting Skip.
8.5.6 Insulation Resistance (IEC60601, AAMI-ES1, VDE0751, IEC62353 and
IEC61010)
Insulation Resistance is a test of the breakdown strength of insulating materials between electrical
conductors that should be electrically isolated from the ground connection at the AC receptacle.
Two tests can be enabled: Line 1+2 to Ground and Applied Parts to Ground. ES601Plus can
perform one of the tests, both tests, or neither.
If Line 1+2 to Ground is checked, ES601Plus will apply a high voltage between the L1 & L2
shorted together and the ground pin at the AC line cord of the DUT that would normally be
connected to protective earth. ES601Plus will measure the resulting current and report the test
result as resistance in megohms.
If Applied Parts to Ground is checked, ES601Plus will apply a high voltage across the applied parts
and the line cord ground pin of the DUT. ES601Plus will measure the resulting current and report
the test result as resistance in megohms. The Applied Parts to Ground test is not provided under the
IEC61010 standard.
