Defibrillator Charge
Check
Shock
hazard.
When
charged
and
discharged
during
this
TCP,
the
defibrillator
discharges
up
to
360J
of
electrical
energy
through
the
defibrillator
electrodes.
Unless
discharged
safely
as
described
in
this
TCP,
this
electrical
energy
may
cause
injury
or
death.
Do
not
attempt
to
perform
this
procedure
unless
you
are
thoroughly
familiar
with
the
operation
of
the
defibrillator.
Shock hazard. Terminals and wires carrying high voltages up to
+11.6kV are exposed with the instrument cases removed. Do not
touch internal circuitry except as indicated in these procedures.
Possible component damage. PCBs in this instrument contain
Static Sensitive Devices (SSDs). Use the Special Handling
Procedures for Static Sensitive Devices described in Section 4 of
your Service Manual to prevent build up of static charge. Refer to
Table 5-1 in your Service Manual to identify PCB assemblies
containing SSDs.
. Remove the Front Panel (see the Disassembly Procedures in
Section 4 of your Service Manual). Press the ON pushbutton on the
Front Panel.
. Use the DMM to monitor the voltage at the J3 pin 25 as shown in
NO TAG (connect the DMM ground to J3 pin 7).
. With the instrument power off, install the Shock Advisory Adapter or
Defibrillation Adapter.
. Remove the battery door on the bottom of the instrument and
disconnect the battery. Connect the DC power supply to the battery
connector inputs. Connect ground to pin 1 or 2 (black wire) and
power to pin 3 4 (red wire).
. Turn the instrument power on and initially set the power supply
output to +18.00 +0.05Vdc.
6. Charge the defibrillator to 360J.
7. Gradually reduce the power supply voltage toward the upper Low
Battery Limit detection threshold of +15.22Vdc.
. With the defibrillator cables attached to the test load connectors, press
both adapter discharge pushbuttons.
. Repeat steps 6. through 8. above, lowering the power supply voltage
toward the lower Low Battery Limit detection threshold of
+14.78Vdc until the LOW BATTERY: CONNECT AC POWER
message is displayed. Confirm that the triggering voltage is within
the Low Battery Limits shown in the Low Battery Thresholds Table.
