Hand-Grip Heart Rate Monitor User Manual

Hand-Grip Heart Rate Monitor

The Hand-Grip Heart Rate Monitor measures a person’s heart rate. Data can be wirelessly transmitted to a Vernier interface using the Heart Rate Receiver. Sensors purchased after May 2015 can also transmit data directly to devices using Bluetooth® wireless technology, such as LabQuest 2, without the receiver. This sensor is ideal for continuously monitoring heart rate before, during, and after exercise or while a person is stationary.

Note: Information in this user manual is for data collection using the Heart Rate Receiver. The preferred method for data collection is wireless data collection using Bluetooth wireless technology. For more information about collecting data wirelessly, see www.vernier.com/manuals/gw-hr

Note: Vernier products are designed for educational use. Our products are not designed nor are they recommended for any industrial, medical, or commercial process such as life support, patient diagnosis, control of a manufacturing process, or industrial testing of any kind.

What's Included

  • Heart Rate Hand Grips
  • Polar Transmitter Module (battery included)
  • Heart Rate Receiver

Compatible Software and Interfaces

The Hand-Grip Heart Rate Monitor may require a compatible interface and software. Choose a platform below to see compatible interface and software options.

Assembly

The Polar Transmitter Module simply snaps onto the hand grips.

Getting Started (with a Heart Rate Receiver)

  1. Connect the sensor to the interface (LabQuest Mini, LabQuest 2, etc.).
  2. Start the appropriate data-collection software (Logger Pro, Logger Lite, LabQuest App) if not already running, and choose New from File menu.

The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.

If you are collecting data using a Chromebook™, please see the following link for up-to-date connection information:www.vernier.com/start/hgh-bta

If you are collecting data on a mobile device such as iPad® or Android™ tablet, please see the following link for up-to-date connection information:www.vernier.com/start/gw-hr

Using the Product (with a Heart Rate Receiver)

  1. Ensure that the Polar Transmitter Module is securely attached to the Heart Rate Hand Grips.
  2. Connect the sensor following the steps in the Getting Started section of this user manual.
  3. The Heart Rate Receiver is marked with an alignment arrow. When collecting data using the receiver, align the arrow on the receiver with the hand grip, as shown here
  4. When using the receiver, make sure that the receiver is held close to the hand grips. The maximum reception range of the plug-in receiver is approximately one meter.

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.

Care and Maintenance

Dirty electrodes on the hand grips can cause poor readings. Between uses, it is a good idea to gently wipe the electrodes clean using alcohol wipes. Do not immerse the hand grips in solution; simply spray or wipe alcohol onto them.

How the Sensor Works

The Hand-Grip 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 hand grips. The heart rate information is then wirelessly transmitted using the Heart Rate Receiver or a Bluetooth radio to supported devices.

Troubleshooting

  • Make sure that the Heart Rate Receiver is aligned with the hand grips.
  • Hold the receiver within 80–100 cm of the hand grips when using the receiver. This is the maximum transmission range of the transmitter when using the receiver.
  • The Heart Rate Receiver can receive signals from other hand grips if they are within range; be sure to maintain a distance of at least 2 m between other individuals that are monitoring heart rate.
  • Interference from electrical devices, such as cell phones, power supplies, and electronic exercise equipment can result in poor readings when using the Heart Rate Receiver. Keep the Heart Rate Receiver as far away as possible from such equipment
  • With certain individuals, readings from the Hand-Grip Heart Rate Monitor may take a minute or two to stabilize. In such cases, allow the readings to stabilize before performing an experiment.
  • 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.
  • If you have a device that supports Bluetooth wireless technology, such as LabQuest 2, use the Bluetooth option for data collection. www.vernier.com/start/gw-hr

Federal Communication Commission Interference Statement

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.
