WARNING: A 2-beep-per-second signal indicates high voltage present at the applied
part terminals while a calibration is being performed.
• When the calibration is finished, the Equivalent Device Leakage test will
reappear.
☛
Note: If the calibration fails the previously stored readings will be used until a
passing calibration has occurred. Also, the esc/stop key has no effect
during calibration.

: VDE Equivalent Patient Leakage Test
The Equivalent Patient Leakage Test measures the current flowing from ALL of the
Applied Parts terminals to the shorted L1, L2 and DUT PE in response to an applied
isolated AC voltage greater than 110% of the Mains voltage. Equivalent Device
Leakage test cannot be selected from the manual menu unless the VDE 751-1 or
VDE 701 test standard is selected.
☛ Note: This test should be performed with a mains voltage > 180 VAC as
specified by the VDE 701 and VDE 751 test standards.
It is recommended that whenever the mains voltage level is changed
(120 VAC to 220 VAC, or 220 VAC to 120 VAC), or when using the
unit for the first time, that a leakage calibration be performed. This can
be done from either of the VDE Equivalent leakage tests or from Mains
on Applied Part.
This test is always performed with all 5 leads.
Important: The Equivalent Patient Leakage test uses the IEC 601-1 Test Load
exclusively. This is true no matter what the currently defined test
standard is.
The following conditions apply:
⇒ Mains supply to DUT L1 and L2 Open
⇒ DUT L1 and L2 shorted to DUT PE
⇒ 110% of mains voltage is applied between individually selected ECG jacks
connected to applied parts and the 601PRO Earth.
