Adjustment: If the trace falls out of tolerance, locate the variable calibration potentiometer ( VR1cap V cap R 1
An isolated serial bus transfers digital data from the A/D converter across an optoelectronic barrier to the central processing MCU. This barrier isolates the patient from dangerous leakage currents. The MCU processes the digital signal using digital filters (EMG, baseline drift, and AC hum filters) and routes the clean data to the thermal printhead driver. 3. Troubleshooting and Hardware Fault Isolation
: Includes automatic baseline adjustment to optimize print quality and reduce drift. Signal Processing : System Overview and Technical Specifications In summary, the
: High-definition matrix thermal array printer supporting standard 50mm or 63mm width roll thermal paper options. Diagnostic Modes & Signal Filtering Subsystems
: Equipped with digital filters for HUM (AC interference) , EMG (muscle tremor) , and ADS (baseline drift) .
Are you running the machine on during the failure? or incorrectly scaled
: The system includes a battery capacity management and protection circuit to prevent excessive discharge.
If the ECG waveforms appear distorted, baseline-shifted, or incorrectly scaled, the device requires calibration. Required Equipment
: Rated as Class I, Type CF under international medical safety standards (IEC 60601-1). It features dedicated floating hardware protection against high-voltage electrical surges from defibrillators and pacemakers.
Verify the integrity of the medical-grade ground (potential equalization conductor). Check patient skin preparation and electrode gel shelf-life.
