8.2 HeartScreen 60G Basic functions
1.
Connect the keyboard, the LCD and the generator.
2. Before downloading the program connect a power supply set to +9V in place of the battery. Remove the resistor.
3. Connect the other power supply – set to 3.6V – to the J17 battery drain point. Connect the negative points of the
two power supplies.
Test procedure Comment
Keyboard test Make sure the appropriate function is performed when the buttons are
pressed.
Speaker test During ECG signal monitoring, if the speaker is turned on.
RTC (clock) test Set the exact date and time, which has to be the same after turning the card
off and on again.
Contrast test The LCD contrast is acceptable, not foggy, the LCD is operational.
Serial data transfer test ECG signal monitoring with Innobase for Windows program and generator,
checking main functions.
Serial data transfer test with SIO
reducing cable ECG signal monitoring with Innobase for Windows program and generator.
Low Batt. check Gradually decrease battery voltage and with it the ONPOWER voltage
level (the processor checks this every second), at 8.4 +/-0.1V a symbol
appears in the bottom right corner:
(ONPOWER J11.9)
Checking power off Continue to decrease the battery voltage (the processor checks this every
second), the device turns off at 7.2 +/-0,1V (ONPOWER J11.9).
Concerning measurement procedures not controlled above, the IEC601/1 safety and IEC 601-2-25 ECG device related
standards are authoritative.
8.3 Checking technical requirements
8.3.1 Safety examinations
In case of repeated examinations the high-voltage sparking examination has to be performed with decreased voltage.
In this case the voltages are at least 80% of the given value.
8.3.1.1 Insulation checking
High-voltage insulation checking has to be performed on the device with the following voltage values:
•
1.5 kVeff between the power supply’s primary and secondary side
•
4 kVeff between the device’s secondary side and the patient connection
•
4 kVeff between the charging adapter connection and the PC -SIO connection
•
4 kVeff between the patient connection and the PC-SIO connection
