  • heartrate monitoring device

    Thanks to everyone that responded. One of the things that I had forgotten
    to mention, and that almost everyone suggested was to "wet" the electrode
    surfaces of the harness with electrode gel. Other suggestions were to make
    the harness as tight as possible (yet still allowing comfort and free
    movement) to insure adequate contact with skin. Next time we have a series
    of labs using this equipment, I'm going to check the skin resistance from
    electrode-to-electrode with a digital ohm meter (ohm meter is very
    sensitive and uses only .5V at a current of micro-Amps so it should be very
    safe to use). This way I can see if skin conductance is actually a factor
    in the performance of the unit.
