Exercise Heart Rate Monitor

Order Code EHR-BTA

The Exercise Heart Rate Monitor 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. Data are wirelessly transmitted to a Vernier interface using the Heart Rate Receiver. Sensors purchased after May 2015 can also transmit data directly to devices that are Bluetooth without the receiver. This sensor is an excellent hands-free option for continuously monitoring heart rate before, during, and after exercise or while a person is stationary.

What is Included with the Exercise Heart Rate Monitor

General procedure for using the Exercise Heart Rate Monitor with the Heart Rate Receiver.

1. Ensure that the Polar Transmitter Module is securely attached to the Exercise Heart Rate Strap.

2. Connect the Heart Rate Receiver to the interface.

3. Start the data-collection software.

4. The software will identify the Exercise Heart Rate Monitor and load a default data-collection setup. 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. Heart rate will be calculated and then graphed during data collection after a short delay.

Data-Collection Software when using the Heart Rate Receiver

This sensor can be used with an interface and the following data-collection software.

 Logger Pro 3 This computer program is used with LabQuest 2, LabQuest,

LabQuest Mini, LabPro, or Go!

 Logger Lite This computer program can be used with LabQuest 2, LabQuest,

LabQuest Mini, LabPro, or Go!

 LabQuest App This program is used when LabQuest 2 or LabQuest is used as a

standalone device. Version 2.2.1, or newer, is required if you are using LabQuest 2. Version 1.7.1, or newer, is required if you are using the original LabQuest.

 DataQuest™ Software for TI-Nspire™ This calculator application for the

TI-Nspire can be used with the EasyLink or TI-Nspire Lab Cradle.

 EasyData App This calculator application for the TI-83 Plus and TI-84 Plus can

be used with CBL 2, LabPro, and Vernier EasyLink. We recommend version 2.0 or newer, which can be downloaded from the Vernier web site, www.vernier.com/easy/easydata.html, and then transferred to the calculator. See the Vernier web site, www.vernier.com/calc/software/index.html for more information on the App and Program Transfer Guidebook.

 DataMate program Use DataMate with LabPro or CBL 2 and TI-73, TI-83,

TI-84, TI-86, TI-89, and Voyage 200 calculators. See the LabPro and CBL 2 Guidebooks for instructions on transferring DataMate to the calculator.

 LabVIEW™ National Instruments LabVIEW™ software is a graphical

programming language sold by National Instruments. It is used with SensorDAQ and can be used with a number of other Vernier interfaces. See www.vernier.com/labview for more information.

This sensor is equipped with circuitry that supports auto-ID. When used with LabQuest 2, LabQuest, LabQuest Mini, LabPro, Go! Link, SensorDAQ, TI-Nspire™ Lab Cradle, EasyLink, or CBL 2™, the data-collection software identifies the sensor and uses pre-defined parameters to configure an experiment appropriate to the recognized sensor.

Collecting Data using Bluetooth

This sensor can also be used with supported mobile devices1 that are Bluetooth® Smart Ready and one of our supported apps. Note: The Heart Rate Receiver is not used when using Bluetooth.

 LabQuest 2 App (version 2.5 or newer)

 Graphical Analysis for iOS devices (version 2.2 or newer) Available on the

App Store. For more information, see www.vernier.com/ga-app

 Graphical Analysis for Android devices (version 2.1 or newer) Available on

Google Play in spring 2015. For more information, see www.vernier.com/ga-app

Collecting Data with Bluetooth Smart Devices

To use the Exercise Heart Rate Monitor with Bluetooth Smart Devices, ensure that the Polar Transmitter Module is attached to the Exercise Heart-Rate Strap securely. Locate and record the ID on the side of the Polar Transmitter Module. This is a unique sequence of eight numbers and/or letters (e.g., ID:XXXXXXXX). Secure the strap around the subject’s chest. The strap should be located just below the chest muscles. Attach the hook to the other end of the strap to secure the sensor. Verify that the Polar Transmitter Module is located in the center of the chest in an upright position. The sensor is now ready for data collection.

Collecting Data with LabQuest 2 App

1. Choose New from the File menu. On the Meter Screen, choose Go Wireless Setup from the Sensors menu.

2. Select the Polar HR with the proper ID from the list of available sensors. Tap OK.

3. The heart rate of the subject will be displayed on the Meter Screen.

4. Collect data as desired.

Note: When done collecting data, tap Disconnect. This will make the sensor available for other devices. If the connection between the device and the sensor is lost, tap Connect and select your Polar HR sensor.

Collecting Data with Graphical Analysis

1. Launch Graphical Analysis.

2. Select Sensor Data Collection.

3. Select the Polar HR with the proper ID from the list of available sensors.

4. Tap Collect to begin data collection.

Note: When done collecting data, tap Disconnect. This will make the sensor available for other devices. If the connection between the device and the sensor is lost using LabQuest, navigate to the Meter Screen. Tap Offline: Heart Rate and select Go Wireless. Tap Reconnect and select your Polar HR sensor.

How the Exercise Heart Rate Monitor Works

The Exercise Heart Rate Monitor 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 chest strap. The heart rate information is then wirelessly transmitted using the Heart Rate Receiver or a Bluetooth radio to supported devices. Note: When using the receiver, make sure that the receiver is held close to the subject. The reception range of the plug-in receiver is 80–100 cm or about 3 feet.

Calibration

The Exercise Heart Rate Monitor does not need to be, nor can it be, calibrated.

Helpful Tips

Listed below are some tips to insure successful data collection.

1. If you have a device that is Bluetooth the Bluetooth option for data collection.

2. Hold the receiver within 80–100 cm of the subject when using the receiver. This is the maximum transmission range of the transmitter when using the receiver.

3. After use, detach the Polar Transmitter Module from the Exercise Heart Rate Strap. Then rinse the strap under running water and hang to dry. Store both items separately to maximize battery life.

4. The Heart Rate Receiver can receive signals from other Polar Transmitter Modules if they are within range; be sure to maintain a distance of at least 2 m between other individuals that are monitoring heart rate.

5. Interference from electrical devices, such as computer monitors, electronic exercise equipment (treadmills, stationary bicycles, etc.), televisions, TV antennas, and high voltage lines (both above and below ground) can result in poor readings. Keep the Heart Rate Receiver as far away as possible from such equipment.

6. 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 performing an experiment. If readings are still unstable, remove the strap from the subject and rinse in running water. This will wet the electrodes. Then reattach to the subject and record heart rate as directed above.
