Taking a Measurement

For reliable readings, follow these steps carefully.

1. Prepare: Rest for 5 minutes before measuring. Avoid eating, smoking, or exercising 30 minutes prior. Sit comfortably on a chair with feet flat on the floor.
2. Apply Cuff: Place cuff on bare upper arm. The bottom edge should be 2-3 cm above the elbow. The air tube should run down the center of your arm. Secure snugly with the cloth closure.
3. Position Arm: Rest your arm on a table so the cuff is at heart level. Relax your hand, palm upward.
4. Start Measurement: Press the START/STOP button. The cuff will inflate automatically. Remain still and quiet until measurement is complete and cuff deflates.
5. Read Results: Your systolic pressure, diastolic pressure, and pulse rate will display. The WHO indicator will show your category.

WARNING! Do not move or talk during inflation and measurement.

Understanding Your Results

The monitor displays key values and indicators.

• Systolic Pressure: Top number (e.g., 120). Pressure when heart beats.
• Diastolic Pressure: Bottom number (e.g., 80). Pressure when heart rests.
• Pulse Rate: Beats per minute (e.g., 72).
• WHO Bar Graph: Color zones indicate classification:
  • Green (Optimal): Below 120/80
  • Yellow (Normal): 120-129 / 80-84
  • Orange (High Normal): 130-139 / 85-89
  • Red (Hypertension): 140+ / 90+
• Irregular Heartbeat Symbol: Appears if an irregular rhythm is detected during measurement. Consult your physician if this appears frequently.

Memory Function

1. Recall Memory: Press the MEMORY button briefly while the monitor is off. The last measurement for the selected user appears.
2. Scroll Through Memory: Press MEMORY again to view previous measurements in reverse chronological order.
3. View Average: After the last stored measurement is displayed, pressing MEMORY again shows the average of the last 3 measurements taken within 10 minutes.
4. Exit Memory: The monitor will automatically power off after a few seconds, or press START/STOP.
5. Clear Memory: Memory is cleared automatically when batteries are removed or when memory is full (oldest reading is overwritten).
