EKG Sensor Troubleshooting and FAQs

Specifications and User Guide

TROUBLESHOOTING
-Primary Test: Confirm that the electrode patches are fresh and connected to the sensor properly. A drawing on the sensor box shows the proper connections. Results vary form person to person. If an individual always has trouble getting a clean signal, try alcohol swabs before affixing the electrodes. The mostly cause of problems with this sensor is a poor connection, either between the tabs and the skin or between the clips and the tabs. Note that electrode tabs do not work as well if they are old or have been allowed to dry out.
-Secondary Test: Make sure that the person connected to the sensor is seated or lying down and that they are relaxed.
