2 The AC impedance of the cardiac electrode reflects the ability to prevent the current from flowing through the electrode interface and the electrode interface.
 
3 The impedance of a pair of glue to glue connections can be determined by applying a sinusoidal wave current with a known amplitude and observing the voltage amplitude of the electrode to both ends The magnitude of the impedance is the ratio of the voltage to the current The peak value of the applied current shall not exceed 100u A.

  • Measurement and calibration

Figure 5.7 Measurement and calibration page
 
l The operation of the defibrillation power supply will output a high voltage of 200V, which may damage the voltage measurement channel, so only used by after-sales personnel of the manufacturer.
 
2 Defibrillation voltage measurement method:
  • Go to the Defibrillation Overload Recovery Test page.
n The positive and negative output of the instrument are connected to the positive and negative poles of the oscilloscope probe, without the load.
n Set the defibrillation voltage of 200 V, and start the defibrillation test.
  • Use the external oscilloscope to see if the defibrillator power supply reaches 200V.
 
l Measurement method of the current source:
  • The AC current source 100uA test circuit is shown in 5.1.2, and the D TU is replaced with a standard resistance of 10KΩ.You need to verify that the peak value of 100uA is the AC power supply, and you can measure the effective value of the AC power source with the multimeter, or view the peak value with the oscilloscope. The measured effective value needs to be converted to a peak value by 2.828. In addition, pay attention to the impact of the input impedance of the multimeter or oscilloscope on the test circuit. It is recommended to choose a voltage measuring device with an input impedance that is greater than 1G Ω.
  • The DC current source 100nA test circuit is shown in 5.1.2.The D TU is replaced with a 10KΩ standard resistance, and the voltmeter input impedance used for all measurements is greater than 10GΩ.
 
  • Voltage measurement measurement method:
The appropriate voltage is input at the voltage measuring end, the input voltage value is measured in three gears of the voltmeter, and compares the test value relative to the actual voltage value to determine the accuracy of the voltmeter.

Inspection and exclusion methods
1

The voltmeter range is too small, stop testing to select a large range of voltmeter retesting.
2
Adjust the current source and voltmeter setting measurement unchanged
The current source and voltmeter parameters shall be adjusted under the test and readjust parameters for test.
3

  • Use the masked space
  • Connect securely to the shield enclosure
