If you are dealing with raw data that is being converted to PDF, the issue might be in the semiconductor interfacing rather than the PDF itself. Ensure robust filtering for power line noise in the configuration settings.
Some common issues with manual ECG semiconductors PDF files include:

| Problem/Symptom | Most Likely Cause | Troubleshooting Steps | | :--- | :--- | :--- | | | Power supply board or keypad. | Check the AC adapter and fuse. Measure voltages on the power supply board. If they are good, suspect the main board. | | Blank Screen | Display failure or connection. | Listen for beeps after power-on. If you hear them, the main board is likely working, and the display or its connection is the issue. | | Noise / AC Interference | Poor grounding, patient prep, or cable. | Verify proper grounding. Re-prep the patient and ensure electrodes are fresh. Try a known-good patient cable. Check if the AC filter setting is correct (50Hz vs 60Hz). | | Baseline Drift / Wander | Patient movement, respiration, or poor electrode contact. | Ask the patient to relax and breathe normally. Check and clean electrodes. Use the Drift filter if available. | | One Lead Fails | Faulty lead wire or patient cable. | Swap leads to isolate. If the problem follows the lead, replace it. If it stays on the same channel, the input amplifier on the main board may be faulty. | | Printer Fails / Poor Quality | Dirty print head, faulty paper, or motor. | Clean the thermal print head with isopropyl alcohol. Check the paper is the correct side up. If the motor doesn't run, check its power and control signals. | This dynamically cancels out body-surface interference

Repairing ECG semiconductors is a high-stakes task. Because these devices are "patient-connected," any "fix" must adhere to standards for medical electrical equipment. Always use medical-grade replacement parts. Never bypass a protection diode or fuse.
