BLOOD PRESSURE
CALIBRATION CHECK
Continued
To perform a calibration check, follow these procedural
steps:
1.
Obtain the calibration kit (Reorder No. 8886) supplied
with the unit.
2.
Connect a mercury manometer (Baumanometer 300, or
equivalent) to the monitor using the parts supplied with
the calibration kit as shown in Figure 6-6. In calibration
procedure, use Adult Cuff and Air Hose.
3.
Plug the monitor into the specified line power outlet.
4.
Clamp off the mercury manometer. Fold the adult cuff in
such a way that the Index Line is in line with the Inner
Range Mark on the inside of the cuff.
5.
Press Front Panel OFF switch then press and hold the
SET switch in for 4 seconds while pressing the Front
Panel ON switch. Flashing 888s in the CYCLE
MINUTES display indicate that calibration mode has
been entered. The monitor will exit calibration mode if
the CANCEL switch is pressed or after 3 minutes of
inactivity. To remain in calibration mode indefinitely,
hold the SET key for 20 seconds. The monitor will
sound a short audio tone and remain in calibration
mode until CANCEL is pressed. Cuff pressure will be
displayed in the MAP display. Allow the monitor to
stabilize for about 30 seconds, then press SET four (4)
times to perform an auto-zero operation.
6.
Using the inflation bulb, manually pump up the
pressure to 200 mmHg,
±
2 mmHg, as indicated on the
MAP display and close pneumatic release valve on
inflation bulb.
7.
Verify that the pressure indicated by the MAP display
does not change more than 5 mmHg in 60 seconds.
N O T E
If the leakdown is greater than 5 mmHg in 60
seconds, isolate the source of the leak to either the
cuff and hose or the monitor using cuff and hose leak
test procedure which follows.
8.
Release clamp from manometer tubing.
9.
Verify that the MAP display (Pressure Reading)
indicates the correct pressure as shown in Table 6-2,
Calibration Check Pressure Levels.
