Sample values produced by these types of
sensors lose accuracy unless the sensors are
allowed to warm up. Perform the following
procedure to ensure better sampling accuracy.
Using a Heart Rate Sensor
1. Select [TRIGGER] as the Trigger Source
item of Advanced Setup's Trigger
parameter.
2. When the EA-100 is in the Ready state
prior to sampling, hold down the EA-100's
[TRIGGER] key for about 20 to 30
seconds, and then release it.
