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.

 Exercise Heart Rate Strap
 Polar Transmitter Module (battery included)

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,

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 six numbers and/or letters (e.g., ID:XXXXXX). 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. Open Graphical Analysis.

2. Tap Create Experiment. Choose Wireless Sensors.

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, 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. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. If you are using the Heart Rate Receiver, you must start data collection to see
heart rate. Live readouts do not display heart rates because that value comes from
a calculated column that must be populated.

7. If you have a device that is Bluetooth

Smart Ready, such as the LabQuest 2, use

the Bluetooth option for data collection.

Suggested Experiments

 Compare the heart rate of

different individuals.

 Compare the heart rate of athletes

and sedentary people.

 Monitor a person’s heart rate

before, during, and after a short
period of vigorous activity (such
as doing jumping jacks).

 Monitor how fast a person’s heart

rate returns to normal after
exercise (recovery rate), as
shown in Figure 1.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. 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.
