The NeuroTherm NT2000 is a multi‑channel radiofrequency generator used in pain management procedures; it supports up to four simultaneous lesions with independent electrode controls via a touchscreen interface and separate output knobs. Common failure points for this class of equipment include power supply issues (faulty fuses or input voltage irregularities), display or touch panel malfunctions, overheating of the internal RF module, and loss of impedance/temperature monitoring due to sensor cable breaks or connector corrosion. First‑check diagnostics should verify the 120 V AC supply and confirm both live and neutral inline fuses are intact; inspect the IEC socket area for signs of arcing or burn marks. Next, review any error codes displayed on the touchscreen and perform a visual inspection of all electrode cables and connectors for fraying or disconnection. Finally, test the output control knobs by attempting to set a low‑power pulse and monitor the temperature/impedance readouts for proper response.[oss-gpt-20b]
