5.2 Software Installation

The Wellue ER1 requires PC software for data download, analysis, and report generation. The software is compatible with both Mac and Windows operating systems.

1. Connect the ER1 device to your computer using the USB cable. The device acts as a USB drive containing the software installer.
2. Locate and run the installer file from the device's storage.
3. Follow the on-screen instructions to complete the software installation.
4. Once installed, launch the Wellue ECG software.

6. Operating Instructions

The ER1 ECG Monitor supports two primary wearing modes for continuous monitoring.

6.1 Wearing Modes

The device automatically begins recording when proper skin contact is established.

6.1.1 Using the Chest Strap

• Attach the ER1 device to the designated clips on the chest strap.
• Position the chest strap around your upper torso, ensuring the device is centered on your chest, just below the sternum.
• Adjust the strap for a snug but comfortable fit. Ensure the device's electrode contact points are firmly against your skin.

6.1.2 Using Disposable Electrodes

• Attach two disposable ECG electrodes to the back of the ER1 device, aligning them with the device's contact points.
• Peel off the backing from the electrodes and apply the device to your chest. For optimal signal quality, place the device diagonally across the chest, typically below the left collarbone and towards the right side of the lower rib cage, or as advised by a healthcare professional.
• Ensure good skin contact. Shaving hair and cleaning the skin with alcohol wipes can improve signal quality.

6.2 Starting and Stopping Recording

The ER1 ECG Monitor features automatic detection. Recording starts automatically when the device detects proper skin contact and stops when contact is lost. There are no manual buttons to press for starting or stopping a recording session.

• To start: Ensure the device is charged and apply it using one of the wearing modes described above. The indicator light may briefly flash to confirm recording has started.
• To stop: Simply remove the device from your body. The recording will automatically cease.

The device can record data for durations ranging from 5 minutes up to 24 hours continuously, capturing up to 100,000 signals.
