Range: Heart rate 0 - 200 bpm Resolution: 1bpm Pulse Waveform Resolution: 1 mV The Heart Rate sensor clip (pleth) holds an infrared LED that shines a light through either the finger or ear lobe and a light sensitive detector. As the amount of light transmitted varies with the flow of blood, the sensor can record either the pulse waveform, or beats per minute. The sensor uses averaging techniques to ensure a smoother reading. In use, the red LED on the sensor housing will flash in time with the heartbeat. Wait for this signal to stabilise before starting a recording. Note: Some subjects may have poor peripheral circulation (the extent to which the blood vessels in the fingertip are filled with blood), in which case another subject should be selected. Some subjects may need to rub their hands together to increase the blood flow. Values should not be affected by skin colouring. For information about this sensor, see the manual.
