Check the watchdog timer also in the infant mode by first selecting Test INFANT from the
menu. The time from the infant test should fall within 60-70 seconds (counter stops +
beep).
Checking the safety valve feature.
Select Safety Valve from the NIBP module menu.
Keep the pressure manometer connected to the cuff connector.
NOTE: Make sure your pressure manometer can be used to measure pressures over 300
mmHg. If such a pressure manometer is not available, perform the check with an adult cuff
that is connected around some round object, for example a calibration gas bottle.
Start the safety valve test by pressing the ComWheel and wait until the pump stops and the
pressure is deflated. Check the pressure value at where the safety valve opened from
beside the text "Max press". The value should be 305 mmHg (±15 mmHg) for both
transducers.
Check also what was the pressure inside the NIBP tubing system at 2 seconds after the
pump stopped. The values beside the text "2 s after stop" should be higher than 280
mmHg. If either of the values is less, check the NIBP tubing system for leakages.
Return to the normal monitoring mode by pressing
Connect an adult NIBP cuff to the cuff connector and disconnect one of its hoses.
Start NIBP measurement by choosing the Start Cycling and check that the message "Cuff
loose" appears on the screen within 30 seconds.
Reconnect the hose and then bend it with your fingers. Restart the measurement and check
that the message "Cuff occlusion" appears on the screen within 30 seconds.
