ES601Plus OPERATING MANUAL
EQUIPMNT:
If set to "ON", leakage tests are performed with the power switch of
the DUT in the "ON" position only. If set to "ON/OFF", leakage
tests are performed with the DUT power switch "ON", and then the
entire leakage test sequence is repeated after the DUT power switch is
set to "OFF".
"DUT OFF" leakage tests are a mandatory requirement of IEC60601
and AAMI-ES1 standards. These standards recognize some types of
equipment do not disconnect from the AC supply when switched
"OFF", but simply enter a standby state in which, for example, an
internal battery is charged. When operating in this state, DUT leakage
may potentially be greater than leakage observed with DUT switched
"ON".
According to IEC60601 and AAMI-ES1, "DUT OFF" is a
supplementary test condition which is required for equipment that
does not fully disconnect from the AC supply when the power switch
is set to "OFF".
POLARITY:
If set to "NORMAL", tests are performed with the AC supply at
normal polarity only. If set to "NORM/REV", tests are performed
with the AC supply in normal and reversed polarities. "NORM/REV"
is the typical setting and is the test requirement specified by all safety
standards.
LINE 2:
If set to "NORMAL", tests are performed with Line 2 (neutral) of the
AC supply in normal condition only. If set to "NORM/OPEN", tests
are performed with Line 2 in normal and single-fault conditions
("open"). "NORM/OPEN" is the typical setting and is the test
requirement specified by most safety standards.
GROUND:
If set to "NORMAL", tests are performed with ground (protective
earth) of the AC supply in normal condition only. If set to
"NORM/OPEN", tests are performed with ground in normal and
single-fault conditions ("open"). "NORM/OPEN" is the typical setting
and is the test requirement specified by most safety standards.
