10. If the indicated pressures are not within tolerance, the
monitor must be calibrated. Refer to qualified service
personnel.
11. Pump up the manometer using the manometer bulb
and, at a pressure between 265 mmHg and 355 mmHg,
verify that the monitor briefly blanks the displays, opens
the deflate valves, and then issues and 800 alarm.
12. If the overpressure point is not within tolerance (300
mmHg
±
30 mmHg), the overpressure switch must be
adjusted. Refer to qualified service personnel.
CUFF AND HOSE
LEAK CHECK
Performing a Cuff and Hose Pneumatic Leak Check
1.
Obtain the calibration kit (Reorder No. 8886) supplied
with this unit.
2.
Connect a digital single-tube manometer with the parts
supplied in the blood pressure calibration kit as shown
in Figure 6-7.
3.
Close the pressure release valve on the manometer
inflation bulb and slowly pump up the pressure to 200
mmHg
±
2 mmHg, as indicated by the manometer.
4.
Verify that the manometer pressure does not fall by
more than 5 mmHg in 60 seconds. If it does, either the
cuff or hose or both may be defective. If the cuff and
hose pass this test reconnect as shown in Figure 6-6.
Pump up the cuff and hose to 200 mmHg,
±
2 mmHg,
and perform the same leak check to determine if the
leak is, in fact in the monitor. Perform this leak check for
all cuff and hose combinations used with the monitor.
