Label Name Function
A Power Cord
Supplies power to the Electrical Safety
Analyzer and to the device under test (DUT).
The measurement circuits are energized when
the power cord is plugged into an outlet. There
is no on/off switch.
B Outlet Indicators
Verify the polarity and wiring of the outlet to
which the Analyzer is connected. Only correctly
wired outlets should be used. Not applicable to
isolated power systems.
C Test Receptacle
Supplies power to the DUT. This outlet is
powered if the OUTLET switch is set to
NORMAL or REVERSED and the NEUTRAL
switch is CLOSED.
D Outlet Switch
If in the center off position, there is no power to
the DUT receptacle. This switch permits testing
with both normal (forward) and reversed
polarity of the line. It is recommended that the
switch be paused in the center OFF position
before changing polarity. Note: Failure to pause
the three-position switch in the OFF position
may cause switch damage or blow the internal
pico fuse.
E Neutral Switch
Permits making leakage current measurements
under the OPEN condition as required by UL
and IEC.
