BeneVision N17/BeneVision N15/BeneVision N12 Patient Monitor Service Manual 3-17
Method 1:
Tools required:
ECG simulator with Sine wave output function.
1. Connect pins of EEG lead wires to an ECG simulator.
Set the ECG simulator to output Sine wave and frequency to between 0.5 and 30Hz. The range is 2mV. The
GND pin of EEG module connects to RL of ECG simulator. The A+ pin of EEG module connects to LA of ECG
simulator. The other pins of EEG lead wires connect to any ECG lead as you wish.
2. Open the EEG setting menu on monitor, Set the Scale of EEG to be 2000uV. Then you can find a Sine
wave on screen of Patient Monitor.
Method 2:
Tools required:
None.
Connect all the pins of EEG lead wire together, for example, you can connect them to some metal
materials. Then check the EEG module resistance test, if all the leads are green then pass.
Method 3:
Tools required:
Resistance box
Multimeter
1. Connect the EEG module/cable to the EEG simulator and the monitor.
2. Set Montage Type: Bipolar Mode.
3. Adjust the resistance box to 1 kΩ, verify the resistance value displayed on the monitor is 1kΩ.
4. Test the lead type of the monitor to B+, C+ and D+ respectively instead of lead A+.
5. Set Montage Type: Monopolar Mode , then repeat the step 3~4.
