Beyond the display, the ECG-1101 series offers a robust set of features:
Scenario: A clinic reports wandering baseline on Lead II, but other leads look fine. Poor manual: “Check electrode contact.” Better manual: “Examine the Wilson network resistors (R112-R117) for tolerance drift. Measure voltage at test point TP7; should be 0V ±10mV. If not, suspect cracked solder joint on the buffer amplifier.” | Possible Cause | Solution | | :---
