pressure applied manually using the rubber bulb.

2. The exhaust condition is displayed in the right portion of the

display from the time of pressurization until the measurement
mark starts flashing.

3. This unit is adjusted so that the exhaust velocity is l -5mm Hg/s

at 150 mmHg.

Note that if this exhaust velocity is not proper, correct

measurements are not possible.

Exhaust Velocity Adjustment

proximately 60mmHg above your

suspected systolic pressure. Hold
the

the figure, and insert

a screwdriver into groove

2. If the exhaust velocity is too fast,

turn to the left and if it is too slow,
turn to the right so that the value
shown in the right portion of the
display is in the range 2 5mm-

Perform this adjustment procedure if the exhaust velocity is not

within the proper range as described above.

1. Apply the arm cuff to the left arm

and pressurize

to the pressure ap-

Hg/s.

When the adjustment is com-

check. If the adjustment is not pro-

per after one try, repeat several

times.

Exhaust velocity will differ

slightly depending upon the size
of the
