- Discharged energy and biphasic pulse phases time - It verifies during the
discharge, that the phase times of both the biphasic pulse and the discharged
energy are within the established limits.
9- PATIENT MONITORING - Is entrustd with testing the part of the equipment in
charge of monitoring the parameters of the patient.
- COMMUNICATION with the ADuC - The CPU tries series communication
with the ADuC. If there is no response within a established time, it considers
that it is not possible to establish communication and returns an error.
- A/D and D/A CONVERTER - In this test it is checked that the converters of
the equipment work correctly.
- Patient IMPEDANCE meter circuit - By means of this Test the impedance
measurement circuit is tested and calibrated.
- ECG CIRCUIT Testing - By means of this Test the impedance measurement
circuit is tested and calibrated
- LOOSE ELECTRODE DETECTION CIRCUIT - This test checks that the
loose electrode detection circuit works correctly, that is that it is capable of
detecting this condition
- Communication with the paddles - The purpose of this test is to check the
correct operation of the I2C bus that communicates with the paddles
10- COPROCESSOR: Presence and communication
The CPU tries to establish series communication with the coprocessor
(COP_RXD0 and COP_TXD0). If it does not respond because it does not exist or
there is some communication problem it will give an error.
11- PACEMAKER - During this test apart from comunication with the Pacemaker, the
following points are tested:
- 125 V Source - The control signal will be viewed to see if the source works or
not.
- Pulse current - The current delivered trough a knwn test impedance is
monitored to verify if it is the same to the one selected during the test.
- Pulse time - Checks that the duration of the pulse provided by the pacemaker is
correct and does not exceed the established limits.
