- Select the appropriate cuff size (22-36 cm or 33-43 cm) for your arm. The cuff should fit snugly but not too tightly.
- Attach the cuff to the monitor's air tube connector.
- Wrap the cuff around your upper arm, ensuring the artery mark on the cuff aligns with your brachial artery. The bottom edge of the cuff should be approximately 2-3 cm above the elbow joint.
- Secure the cuff firmly using the hook-and-loop fastener.
3.3 Software Installation
The ABPM software is provided on the included USB disk. Insert the USB disk into your PC and follow the on-screen instructions to install the software. The software is compatible with Microsoft Windows operating systems (Win2003/WinXP/Win7/Win10/Win11).
3.4 Connecting to PC
To transfer data or program the device, connect the monitor to your PC using the provided USB data cable. Ensure the software is running on your PC.

4.3 Data Transfer and Analysis with PC Software
After completing a monitoring session, connect the device to your PC to transfer the stored data. The software allows for comprehensive analysis:
- Advanced ABPM Analysis: Gain insights into nocturnal hypertension, morning surges, and correlations between DIA vs SYS and HR vs SYS. The Ambulatory Arterial Stiffness Index (AASI) can also be analyzed.
- Trend Graphs: Visualize up to 72 hours of data, showing blood pressure variations over time.
- Customizable Reports: Generate professional PDF reports. You can define report content, set hospital logos, and include signatures.
- Data Management: User-defined data saving paths, patient search function, and comparison of BP between different measurements for the same patient.
- Visual Customization: Set colors for systolic, diastolic, sleep period, and BP limits to suit individual preferences.
