| Parameter | Specification | |-----------|---------------| | Leads | Standard 12 leads (I, II, III, aVR, aVL, aVF, V1–V6) | | Acquisition | Simultaneous 12-lead acquisition, single-channel print | | Frequency Response | 0.05 Hz – 150 Hz (diagnostic mode) | | Input Impedance | > 50 MΩ | | CMRR | > 100 dB | | Paper | 50 mm or 63 mm roll, thermal | | Power | AC 110–240V, 50/60 Hz; internal rechargeable battery | | Safety Class | CF type (isolated patient input) | No manual is perfect

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.” This living document turns a good service manual

Result: Technician finds a cold solder joint. Repair cost: $0. Downtime: 2 hours.

| Frequency | Action | |-----------|--------| | Monthly | Clean thermal print head with isopropyl alcohol and lint-free swab. Inspect patient cable for cracks. | | Quarterly | Measure leakage current (patient leads to ground): should be < 10 µA. Run 1 mV calibration check. | | Annually | Full gain, speed, and filter frequency verification using calibrated simulator. Replace paper roll to avoid dust buildup. |
