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 AAMI-ES1 and
IEC60601 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 AAMI-ES1 and IEC60601, "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.
NEUTRAL:
If set to "NORMAL", tests are performed with Neutral of the AC supply in
normal condition only. If set to "NORM/OPEN", tests are performed with
Neutral 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 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.
PATIENT LEADS:
If set to "TEST", measurement of patient lead leakage is enabled. If set to
"DO NOT TEST", patient lead leakage is disabled. All safety standards
require patient leads to be tested if the DUT provides patient leads (e.g.:
ECG leads; blood pressure transducer; temperature probe; SpO2 probe;
etc).
