EMP TEMPERATURE
1. Connect the TurboTemp™ Hi-Pot cable to the ground test lead
of the Hi-Pot tester. Attach the red test lead to “Hot/Neutral.”
Test at 4242VDC.
2. Connect the TurboTemp™ Hi-Pot cable to the red lead of the
Hi-Pot tester and connect the ground test lead of the Hi-Pot
tester to the DB9 shell of the 506N3. Test at 2121VDC.
3. If the monitor has DOX SpO
2
, red lead of the Hi-Pot tester to the
DOX SpO

Leakage Testing
This test requires a Dynatech 232D Safety Analyzer (or equivalent)
leakage testing device.
Setup Procedure
(Self-Test)
Perform a self test, if applicable, to ensure proper operation of the
leakage tester. If the self test fails, don’t proceed with this test.
For Dynatech 232D only :
1. Perform a self test on the Dynatech 232D. Set the MODE switch
to SELF test. The display should read 1000
(±
20) and the
CURRENT SOURCE ACTIVE lamp should be on.
• If these conditions are not met do not continue with the leakage
test.
2. Set the MODE switch on the Dynatech to L1-L2. The display
should read 220 to 240 VAC (or 110 to 130 VAC if supply
voltage is 120 VAC). Set the MODE switch to L1-GND. The
display should read no more than 5% of the previous line
voltage measurement. Set the MODE switch to L2-GND. This
reading should be the same as the first reading,
±
5 VAC.
