Here are some tips to insure successful data collection with the Exercise Heart Rate Monitor:
(1) Make sure that the belt fits snugly around the chest and is resting directly against the subject’s skin. You may need to reposition the transmitter left or right, or place it lower or higher. Make sure to re-wet the electrodes each time the belt is repositioned.
(2) Use plenty of saline solution to wet the electrodes.
(3) Be sure to hold the receiver within 80 cm of the transmitter belt. This is the maximum transmission range of the transmitter in the chest belt.
(4) The receiver of the Exercise Heart Rate Monitor will receive signals from other transmitter belts if they are within range; be sure to maintain a distance of at least 2 meters between individuals that are wearing this sensor.
(5) Interference from other electrical devices, such as computer monitors and electronic exercise equipment (treadmills, stationary bicycles, etc.), can result in poor readings. Other equipment that may interfere with the EHR signal include televisions, cars, cellphones, TV antennas, and high voltage power lines (both above and below ground). Keep the receiver of the Exercise Heart Rate Monitor as far away as possible from such equipment.
(6) Static electricity in clothing or a flapping shirt can cause electrical interference, so some items of clothing (i.e. man-made fibers) can also cause unusual readings.
(7) Dirty electrodes can cause poor readings. Wash the transmitter regularly after use with a mild soap and water solution. Dry carefully with a soft towel after washing. Do not use alcohol or a solvent based detergent.
(8) With certain individuals, readings from the Exercise Heart Rate Monitor may take a minute or two to stabilize. In such cases, allow the readings to stabilize before clicking on the Collect button.
