5. Prepare an SPM/DPM pressure adapter by cutting a DPM/SPM filter
with four inches of tubing from a disposable set. Remove the nipple
from the sphygmomanometer and insert the filter tubing onto the
sphygmomanometer.
6. Install the filter onto the DPM and pressurize the sphygmomanometer
to 300 mmHg.
7. Press the RETURN key to store the DPM Full Scale value.
8. Remove the filter from the DPM.
9. Exit A/D Calibration by pressing the STOP key, then exit Calibration
by pressing the STOP key again. Toggle the write protect switch on
the Processor Card when instructed to, then replace the rear access
panel. Pay particular attention to prevent disconnection or kinking of
the pneumatic lines around the compressor and the cuff connector.

4. Install a bowl into the centrifuge.
5. Close and latch the centrifuge cover.
6. Press the DRAW key to start the centrifuge at a set speed of 8000 rpm.
7. Press the YES or NO keys to adjust the actual speed to 8000 ± 30
rpm. Each key press changes the outval value by one digit, resulting in
a new centrifuge speed. Wait five to ten seconds between key presses
to allow the centrifuge speed to stabilize.
8. If the centrifuge does not reach 8000 rpm, set outval to 255. Using the
potentiometer R68 on the Centrifuge Driver Card, increase speed until
the display reads 8200 rpm. Lower outval back down using YES/NO
keys until actual speed is 8000 ± 30.
