pin at the ground pin location to aid mechanical retention of the Power Brick
into the receptacle.)
Dielectric strength (“Hi-Pot”) testing of the double (reinforced) mains
insulation (4000 V RMS, 60 Hz) may be done by disconnecting the Power
Brick from the Monitor and applying the Hi-Pot tester as follows: Connect
one lead to the two mains power prongs. Connect the other lead to the
conductive sleeve on the DC output connector at the end of the cord.
Hi-Pot testing of the patient connections (1500 VRMS, 60 Hz) may be done
by connecting one lead of the Hi-Pot tester to the outer shell of a spare DC
connector plug inserted into the DC input connector on the Monitor. The
other lead of the tester should be connected to the patient connection being
tested.
WARNING: Don’t electrocute yourself or anyone else when performing Hi-
Pot testing.
NOTE: Hi-Pot testing is done on every unit at the factory and should not be
repeated unnecessarily nor performed more often than required.
4.5.1 Temp Circuit Leakage Test
1. Setup an IEC 601-1 approved leakage tester to apply 240 VAC to an
isolated circuit.
2. Plug temp probe Hi Pot adapter into the temp jack.
3. Record and verify the temp circuit leakage current.
