How the Go Wireless Heart Rate Works

The Go Wireless Heart Rate measures a person’s heart rate by registering the small electrical signals carried across the surface of a person’s skin each time his or her heart contracts. The Polar Transmitter Module detects each electrical signal from the heart through the electrodes on the hand grips. The heart rate information is then wirelessly transmitted using a Bluetooth radio to supported mobile devices.

Collecting Data with Bluetooth Smart Devices

Ensure that the Polar Transmitter Module is attached to the Heart Rate Hand Grips securely. Locate and record the ID on the side of the Polar Transmitter Module. This is a unique sequence of six numbers and/or letters (e.g., ID:XXXXXXXX). Have the subject grasp the handles of the Go Wireless Heart Rate to activate the Bluetooth radio in the Polar Transmitter Module. The sensor is now ready for data collection.

Collecting Data with Graphical Analysis

Launch Graphical Analysis.
Select Sensor Data Collection.
Select the Polar HR with the proper ID from the list of available sensors.
Tap Collect to begin data collection.
Note: The sensor will disconnect from the device 30 seconds after letting go of the hand-grips. To reconnect to the sensor, tap Connect and select your Polar HR sensor..

Collecting Data with LabQuest App

Choose New from the File menu. On the Meter screen, choose Wireless Device Setup ► Go Wireless from the Sensors menu.
Select the Polar HR with the proper ID from the list of available sensors. Select OK.
The heart rate of the subject will be displayed on the Meter screen.
Collect data as desired.
Note: The sensor will disconnect from the device 30 seconds after letting go of the hand-grips. To reconnect to the sensor, navigate to the Meter screen. Tap Offline:
Heart Rate and select Go Wireless. Tap Connect and select your Polar HR sensor.

Collecting Data without a Bluetooth Smart Device

his sensor can also be used with a Vernier interface and a Heart Rate Receiver (HR-REC, not included). Here is the general procedure to follow when using the Go
Wireless Heart Rate with a Vernier interface that is not Bluetooth Smart.

Connect the Heart Rate Receiver to the interface.
Start the data-collection software.
The software will identify the Go Wireless Heart Rate as a Hand-Grip Heart Rate Monitor. A default data-collection file will be opened.
You are now ready to collect data. *Note: The subject’s heart rate will not be displayed on the Meter screen when using the Heart Rate Receiver with the Heart Rate Hand Grips. Heart rate will be calculated and then graphed during data collection after a short delay.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
