Follow this procedure to perform the test:
1.
Connect the equipment as shown below.
Manometer
Monitor
Tubing
Connector for NIBP cuff
Squeeze bulb
2.
Rigid vessel
Before inflation, the reading on the manometer should be zero. If not, disconnect the squeeze bulb to release any
pressure. Reconnect the squeeze bulb and verify that the pressure reading is zero.
3.

4.
Check the manometer values and the monitor values. Both should be 0 mmHg.
5.
Raise the pressure in the rigid vessel to 50 mmHg with the squeeze bulb. Then, wait for 10 seconds until the measured
values become stable.
6.
Compare the manometer values with the monitor values. The difference should be within ±3 mmHg.
7.
Raise the pressure in the rigid vessel to 200 mmHg with the squeeze bulb. Then, wait for 10 seconds until the measured
values become stable and repeat step 6.

A Electrical Safety Inspection
The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They
are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the
operator. Additional tests may be required according to local regulations.
All tests can be performed using commercially available safety analyzer test equipment. Please follow the instructions of the
analyzer manufacturer.
The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is emphasized as a mandatory step if
an approved agency status is to be maintained. The safety analyzer also proves to be an excellent troubleshooting tool to
detect abnormalities of line voltage and grounding, as well as total current loads.
