Service Manual BSM-4100 3.33

3. Safety Check

There are the following 6 check items monitored by the NIBP safety circuit.

Check item Description Range

PRESS 1 Pressure limiter in the adult mode 315 +/− 15 mmHg

PRESS 2 Pressure limiter in the neonatal mode 157.5 +/− 7.5 mmHg

TIME 1 Time limiter in the adult mode 176 - 180 sec ( >15 mmHg )

TIME 2 Time limiter in the neonatal mode 86 - 90 sec ( >5 mmHg )

TIME 3 Interval error in the adult mode >=10 sec ( >15 mmHg )

TIME 4 Interval error in the neonatal mode >=10 sec ( >5 mmHg )

NOTE

Since the TIME 1 to TIME 4 checks require a pressure generator which

supplies a pressure such as more than 5 mmHg or more than 15 mmHg

during a certain period such as 3 or 1.5 minutes or supplies the

pressure at a certain interval such as 10 seconds, do not perform these

checks locally.

Connect the manometer and hand bulb pump to the dummy cuff using the Y-shape

connector and connect the dummy cuff to the instrument with the air hose as

shown below.

For the PRESS 1, use the YN-901P air hose.

For the PRESS 2, use the YN-921P air hose.
