TROUBLESHOOTING
NO TEMPERATURE READING ON THE THERMOCOUPLE ELECTRODE
•
Check the electrode for any visual defects.
•
Plug the electrode into the NT2000iX
1 LED changes from red to green on the front panel of the generator. If it stays red, the thermocouple may be
damaged. Replace the electrode.
•
Place the electrode tip into 50 °C water to see if the temperature display changes to the water temperature.
If it does not, the thermocouple may be damaged.
NO STIMULATION FELT BY PATIENT
•
Is the grounding pad affixed to the patient correctly? (Refer to the grounding pad "Instructions for Use"
for proper placement.)
•
Is the grounding pad the correct size (16 square inches of surface area)?
•
Is the grounding pad cable connected to the NT2000iX RF generator?
•
Is the electrode connected to the correct input socket as shown by the Probe LED?
•
Is the electrode the correct length for the needle, for example, 10 cm electrode with a 10 cm needle?
•
Are thermocouple electrodes and RF needles being used?
WILL NOT REACH TEMPERATURE
•
Is the grounding pad affixed to the patient correctly?
•
Is the grounding pad cable connected to the NT2000iX RF generator?
•
Is the electrode the correct length for the needle, for example, 10 cm electrode with a 10 cm needle?
•
Is the needle placed close to a blood vessel? High blood flow may cool the needle.
•
Is the average impedance reading of the patient normal (200 to 800 ohms)? If not, try to reduce the
impedance by repositioning the needle/electrode.
