How The Blood Pressure Monitor Works

The graph above illustrates the variations over a single day with measurement taken every 5 minutes. The thick line represents sleep time. The rises in blood pressure at 4PM (A in the graph) and 12AM (B in the graph) correspond to an attack of pain and sexual intercourse (Beven, Honour & Stott, Clin. Sci. 36:329, 1969).

How The Blood Pressure Monitor Works

This product uses the Oscillometric Measuring method to detect your blood pressure. Before every measurement, the unit establishes a “zero pressure” equivalent to the air pressure.

Then it starts inflating the wrist cuff to 180mmHg or higher until it senses that it has blocked your blood in the artery. After that, the deflation process starts,

during which time the unit detects pressure oscillations generated by beat-to-beat pulsatile, which is used to determine the systolic, mean and diastolic pressure, and also your pulse rate. Any motion during this period will result in an incorrect measurement. After all readings are determined and displayed on the LCD, the measurement is finished and the wrist cuff automatically deflates.

Getting Started

Installing And Replacing The Batteries

1.Slide off the battery cover.

2.Install the batteries by matching the correct polarity, as shown below. Always use the correct battery type (2 alkaline LR03 AAA-size).

3.Replace the cover.

NOTE: Replace the batteries whenever the weak battery

mark shows, the display is dim, or the display does not illuminate when the power is on. Replace

all the batteries at the same time - it is dangerous to mix old and new batteries. Contact your local waste disposal authority for instructions on how to dispose of used batteries. Used batteries can be harmful to the environment, and should not be thrown out with household trash.

Setting Date, Time And Measurement Units

It is important to set the clock before using your blood pressure monitor, so that a time stamp can be assigned to each record that is stored in the memory.

1.When the unit is off, press and hold SET for 2 seconds to enter the setting mode.

2.The setting order is as follows: 12/24 hour format, hour, minute, year, month/day or day / month format, month, date, and measurement unit (kPa or mmHg).

3.Press or to increase / decrease a value or change the setting.

4.Press SET to accept the change and switch to the

next setting.

5.When you are finished, press to exit the setup menu.

Positioning The Wrist Cuff

It is important to properly position the wrist cuff to ensure that you receive an accurate reading.

1.Remove all accessories (watch, bracelet, etc.) from your left wrist. If your physician has diagnosed you with poor circulation in your left arm, use your right wrist.

2.Roll or push up your sleeve to expose the skin.

3.Apply the cuff to your left wrist with your palm facing up.

4.Position the edge of the cuff about 0.4 inches (1cm) from the bottom of your palm.

5.Fasten the wrist cuff around your wrist, leaving no extra room between the cuff and your skin. If the cuff is too loose, the measurement will not be accurate.
