23.0NIBP Transducer Calibration Test
The NIBP module’s pressure transducers are factory-calibrated prior to shipment. However, you can perform a two-point calibration procedure
periodically to ensure accurate pressure measurements.
This test should be performed annually or every 10,000 readings, whichever comes first.
Tools Needed: NIBP simulator (The values and procedure provided in this manual are specific to the BP Pump 2)
Test Setup:
1. Connect the simulator’s hose to the NIBP connector on the R Series unit.
2. Configure the NIBP simulator to simulate cuff pressure. For example, on the BP Pump 2
7
:
• Press the MODE button three (3) times to go into Tests mode.
• Press the SELECT button once to access the Pressure Simulator screen.
3. Make sure the ECG cable is not connected to the R Series unit.
4. If the SpO
2
option is installed, make sure that the SpO
2
patient cable is NOT connected to the R Series unit.

These instructions apply to the BP Pump 2; for equivalent devices, follow the manufacturer's instructions.

23.1 Turn the Selector Switch to OFF.
After 10 seconds, press and hold the fourth
softkey from the left and turn the Selector
Switch to MONITOR.(AED units to ON)
The R Series powers on in the NIBP Service Mode.
23.2 Press the NIBP Calib softkey. The R Series displays the NIBP Transducer Calibration Screen.
23.3 On the NIBP simulator, set the pressure
parameter to 0 mmHg.
The NIBP simulator displays a pressure reading of 0 mmHg.
23.4 On the R Series unit, press the Set Low softkey
to calibrate the transducer to a 0 mmHg
pressure reading.
The NIBP pressure transducer registers its voltage output at a known pressure
of 0 mmHg. The field adjacent to the 0 mmHg value changes to PASS.
Note: If the R Series displays a FAIL reading, verify the NIBP simulator’s
pressure setting and connection to the R Series and repeat the step.

23.5 On the NIBP simulator, set the pressure
parameter to 250 mmHg.
The NIBP simulator displays a pressure reading of 250 mmHg.
