Vu Heart rate Sensor



Heart rate

Range: 0 to 200 bpm

Resolution: 1 bpm



Waveform

Range: -2,000 to 2,000 mV

Resolution: ±4 mV

The Heart Rate sensor sensing clip (pleth) holds an infrared LED that shines a light through

either a finger or ear lobe onto a light sensitive detector. As the amount of light transmitted

varies with the flow of blood, the sensor can record either blood flow (heart waveform), or

heart rate (beats per minute).

Note: This sensor is only suitable for use with the Vu data logger.

Connecting



Push one end of a Vu sensor cable into the shaped socket on the sensor's housing and

the other end to an input socket on Vu.



Insert the jack plug from the finger/ear lobe clip into the jack socket of the of the sensor

housing.



Vu will detect that the Heart rate sensor is connected and display values using the

currently selected range.

Measurement procedure

Note: This sensor works best if the test subject keeps the finger with the sensing clip still.



Attach the sensing clip to either the fingertip or to the ear lobe.



Sit still as any muscle movements will influence the signal. The red LED on the sensor

housing will start to flash in time with the heartbeat - wait for the signal to settle (approx.

10 seconds). If the clip is attached to the finger you may feel a throbbing sensation.



Once a regular heart rate is detected, begin recording data.
