Exhaust velocity is the rate at which the air pressure in the cuff deflates during the course of measurement. It is preset at the factory and generally does not need any further adjustment.
NOTE: The exhaust rate of your monitor was preset and tested at the factory to ensure proper measurement. The rate set is dependent on cuff size, not arm size. If using a cuff other than the one shipped with the unit, you may need to adjust the exhaust velocity rate. There is no need to adjust exhaust velocity when changing between a medium cuff and a large cuff with a valve.
To check the exhaust velocity rate, proceed as follows:
1.Put on the arm cuff.
2. Press the START button.
The unit will begin taking a reading.
3.Watch the display screen as the cuff deflates. When the MEASUREMENT IN PROGRESS symbol appears,
the numbers should decline in increments of 2 to 5 mmHg.

If the exhaust velocity range is not within 2 to 5 mmHg, make the following adjustment with the unit turned off:
1.With the edge of your fingernail, peel off the thin black plastic disk covering the adjustment screw. If there is no thin plastic disk, proceed to step 2.
REMOVE THE COVER
FROM THE
ADJUSTMENT SCREW
2.Using a small screwdriver, rotate adjustment screw about
45 degrees clockwise (to raise the rate) or counterclockwise (to lower the rate).
3.Repeat the test until the exhaust velocity is between 2 and 5 mmHg.
NOTE: Once the monitor is adjusted to a new cuff size, further adjust- ments should not be required unless cuff size is changed again.
