Preventative Maintenance Tests

Testing the Monitor  

This test verifies the deflation rate of the monitor.

1

Turn the simulator on.

2

Perform the following sequence:

a. Press the Home button.
b. Press the Pressure Tests button.
c. Press the Pressure Leak Test button.
d. Set the Cuff to Internal.

3

Confirm that the simulator is active and displays "Leak Test".

4

Press  the  Volume button to ensure that both valves are closed.

5

Perform an offset adjustment so that the simulator and monitor both display a 
pressure of 0 mmHg or kPa by doing the following:

a. Press the Contrast button on the monitor’s front panel.
b. If needed, zero the simulator (see “To Zero the Simulator” on page 4-16).

6

Note—Complete steps 6-9 within 150 seconds. 

Press and hold the NBP button on the monitor’s front panel and inflate to 250 
±10. Don’t go over 270, or safety deflation may occur. (Slow the inflation rate by 
pulsing the button when the pressure is over 200).

7

Allow 15-20 seconds for the pressure to stabilize. Record the pressure displayed 
on the monitor (P1).

8

Press and hold the "Alarm off" button on the monitor to release the pressure in 
steps of 3 mmHg (.4 kPa). Simultaneously, start the timer.

9

Stop the timer when the pressure drops below 150 mmHg (20 kPa). Calculate the 
deflation rate (X5): (starting pressure - 150)/# of seconds. The deflation rate 
should be 3.3 mmHg/s ±1.5 mmHg/s (0.44 kPa/s ± 0.2 kPa/s).

10

Press and hold the Volume button until the monitor displays a pressure of 0 
mmHg or kPa.

11

If no further NBP tests are to be conducted, turn the monitor Off. Normal 
monitoring operation returns the next time the monitor is turned On.
