Choosing the right cu
For accurate measurement, it is important to choose the correct size cu which best ts your upper
arm. Choose the cu size according to your arm circumference and make sure the bottom of the cu is
2~3cm above your elbow.
• Small/Medium Cu = 22~32cm arm circumference
• Large/XLarge Cu = 32~42cm arm circumference
Applying the arm cu
1. Slide the end of arm cu furthest from the tube through the metal ring to a loop.
The smooth cloth should be on the inside of the cu.
2. Plug the air hose into the connector (Fig. 4).
3. If the cu is located correctly, the velcro will be on the outside of the cu and the metal ring will
not touch the skin (Fig. 5).
4. Put your left arm through the cu loop. The bottom of the cu should be approximately (2~3 cm)
above elbow. The tube should lie over the brachial artery on the inside of the arm (Fig. 6).
5. Pull the cu so that the top and bottom edges are tightened around your arm (Fig. 7).
6. When the cu is positioned properly, press the Velcro rmly against the pile side of the cu.
7. This cu is suitable for use if the <<index>> mark falls within the <<ok range>> marked by two
arrows when the cu is tightened around your arm (Fig. 8).
8. Sit on a chair and place your arm on the table so that the cu is at the same level as your heart
(Fig. 9).
