Check the thermal printer head for debris and ensure the thermal paper is loaded with the sensitive side facing the head.
The device operates in three modes: (fully automatic recording), Manual (user‑controlled recording), and Analysis (which provides measurement and interpretation of the ECG signal). It is manufactured by Shenzhen Carewell Electronics Co., Ltd..
If the cable connecting the touch screen to the main board is defective or loose, the screen will not respond. If the cable is intact but the "touch position is invalid," the touch screen may need to be calibrated from the internal settings of the ECG machine.

The Carewell ECG 1101 is a portable electrocardiogram (ECG) device used for monitoring and diagnosing cardiac conditions. Like any medical equipment, it requires regular maintenance and occasional repair to ensure accurate and reliable performance. This report provides a comprehensive guide for fixing common issues with the Carewell ECG 1101, based on the service manual and technical specifications.
The Carewell ECG 1101 utilizes a Right Leg Drive circuit to cancel common-mode noise. If AC interference persists even when a simulator is attached, inspect the operational amplifiers (op-amps) associated with the RL circuit on the analog board.
The ECG 1101 relies heavily on its internal rechargeable battery. If the battery is deeply discharged or completely dead, the device may refuse to boot even on AC power. Disconnect the battery and measure its voltage with a multimeter. If it reads significantly below its rated voltage, replace it.
