CALIBRATION CHECK
Continued
To perform a calibration check, follow these 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 6-9. 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
