Troubleshooting and Tech Tips
- Make sure the power cord and patient cable do not cross and are as far apart as possible.
- Make sure all electrodes have good skin contact.
- The reference-lead is always the right leg. Make sure this site has been thoroughly abraded and that there is good electrode to skin contact.
- Patient cannot be in contact with other electrical equipment or wall.
- Insufficient skin preparation
- Patient moving during recording
- Poor application
- Tense patient
Solution: Assuming good skin preparation and electrode application, allow a short time for the electrodes to stabilize, then repeat the recording. Arm lead hook-ups should be as close to the shoulder as possible. Very tense patients should be instructed to sit on their hands with palms facing down.
