Setup
1. Checking Arm Circumference
Before using the cuff, measure the circumference of your left upper arm, midway between your elbow and shoulder. The HEM-CS24-B cuff is designed for arm circumferences between 7 and 9 inches (17 to 22 cm). Using an incorrect cuff size can lead to inaccurate readings.
2. Attaching the Air Plug
Insert the air plug of the cuff firmly into the air jack of your compatible Omron blood pressure monitor until it clicks into place.
3. Applying the Cuff

Image Description: A gray Omron D-ring blood pressure cuff with an attached gray air tube and blue connector. The cuff has diagrams printed on it illustrating how to position it on the arm, indicating a 1-2 cm (1/2 inch) distance from the elbow and an arm circumference range of 17-22 cm (7-9 inches).
- Sit in a chair with your feet flat on the floor and your arm resting on a table so the cuff is at heart level.
- Slide your left arm through the cuff loop. The air tube should run down the inside of your arm.
- Position the cuff so the bottom edge is approximately 1 to 2 cm (0.5 inches) above your elbow. The air tube should be centered on the inside of your arm, aligned with your middle finger.
- Wrap the cuff snugly around your upper arm. The fabric fastener should be secure, but not uncomfortably tight. The 'INDEX' arrow on the cuff should fall within the 'RANGE' indicated on the cuff.
Operating
Taking a Measurement
Once the cuff is correctly applied and connected to your Omron blood pressure monitor, follow the instructions provided with your specific monitor model to initiate a blood pressure measurement. Ensure you remain still and quiet during the measurement process for accurate results.
Maintenance
- Cleaning: Wipe the cuff gently with a soft, dry cloth. If necessary, use a soft cloth dampened with water and mild soap, then wipe dry. Do not wash the cuff in a washing machine or immerse it in water.
- Storage: Store the cuff in a clean, dry place away from direct sunlight, extreme temperatures, and humidity. Avoid folding the air tube sharply.
- Inspection: Periodically inspect the cuff and air tube for any signs of damage or wear. If damage is observed, discontinue use and replace the cuff.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Incorrect cuff size, improper cuff placement, movement during measurement. | Ensure cuff fits arm circumference (7-9 inches). Re-apply cuff correctly as per instructions. Remain still and quiet during measurement. |
| Cuff does not inflate or inflates improperly | Air plug not securely connected, air leakage from cuff or tube. | Check that the air plug is fully inserted into the monitor. Inspect cuff and tube for any visible damage or leaks. |
| Cuff is uncomfortable | Cuff applied too tightly or too loosely. | Adjust the cuff to be snug but not uncomfortably tight. Ensure the 'INDEX' arrow is within the 'RANGE'. |
