BeneVision N22/BeneVision N19 Patient Monitor Service Manual 3-13
3.4.5 Temp Test
Tools required:
 Resistance box (with accuracy above 0.1 Ω)
1. Connect the two pins of any Temp connector of a module to the two ends of the resistance box using two wires.
2. Set the resistance box to 1354.9 Ω (corresponding temperature is 37ºC).
3. Verify each Temp channel of the monitor and make sure that the displayed value is within 37±0.1ºC.
4. Repeat steps 1 to 3 to verify each Temp channel of the monitor.
3.4.6 IBP Tests
Performance Test
Tools required:

Patient simulator Medsim300B, MPS450, or other equivalent equipment
 Dedicated IBP adapter cable (P/N 00-002199-00 for 300B, P/N 00-002198-00 for MPS450)
1. Connect the patient simulator to the monitor's IBP connector.
2. Set the patient simulator output to the IBP channel to 0 mmHg.
3. Press the Zero key on the module to make a zero calibration.
4. Set static pressure to 200 mmHg on the patient simulator.
5. The displayed value should be within 200±2 mmHg.
6. If the error is beyond ±2 mmHg, calibrate the IBP module. If the IBP module was calibrated with a dedicated
reusable IBP sensor, check the calibration together with this IBP sensor.
7. Make the patient simulator outputs 120/80 mmHg ART signals and 120/0 mmHg LV signals respectively to each
IBP channel and check that the IBP wave is displayed correctly.
8. Repeat the preceding steps to test all IBP channels.
Pressure Calibration
Method 1:
Tools required:
 Medsim300B patient simulator, MPS450, or other equivalent equipment
 Dedicated IBP adapter cable (300B, P/N 00-002199-00) (use P/N 00-002198-00, if the simulator is MPS450)
1. Connect the patient simulator to the monitor's IBP connector.
2. Set the patient simulator to 0 pressure for the desired IBP channel.
3. Press the Zero key from the IBP menu.
4. Set static pressure to 200 mmHg on the patient simulator.
