For the cervical spine, take your free hand, and lift the hair up with it. Bend the head forward slightly. You can re-scan at this time. If there is excess skin, or there is moisture on the skin, readings will be high. Clean the skin with Alcohol, and then dab the skin dry before re-testing.
Worn electrodes prevent proper skin contact.
As they become worn, readings will become increasingly more erratic, as skin contact becomes poorer over time. Replace your static electrodes every 6 months or after approximately 200 tests. Electrodes that are light gray, blotchy or have turned shiny should be replaced immediately. If readings are high and don t settle when you touch down to the skin, simply lift the probes off the skin, move in any direction approximately 1-2 inches or so, and touch down again. If the condition of the skin is not conducive to providing good readings, many times simply moving the probes a bit over on the skin will create better skin contact.
