Here is the general procedure to follow when using the Hand-Grip Heart Rate Monitor:
Hand-Grip Heart Rate
1. Connect the Hand-Grip Heart Rate Monitor receiver to the interface. 2. Start the data-collection software.
3. The software will identify the Hand-Grip Heart Rate Monitor and load a default
data-collection setup. You are now ready to collect data.

In general, you can use the Hand-Grip Heart Rate Monitor as you would any other
sensor connected to your interface. You can plot a pulse for each heart beat and
analyze the time between the peaks to determine the heart rate. Often it is more
convenient to use a program that simply displays the heart rate in beats per minute
on the screen. Our data-collection programs perform this task for all of our interfaces.
Do I Need to Calibrate the Hand-Grip Heart Rate Monitor? “No.”
The Hand-Grip Heart Rate Monitor does not need to be, nor can it be, calibrated. It
provides very accurate heart rate values.
Using a Chest Belt Transmitter The Chest Belt Transmitter, which is ordered separately (Order Code CBT), works in place of the hand grips, allowing a hands-free option of measuring heart rate. The chest belt is worn on or below the chest and held in place by an elastic strap. Make
sure that the belt fits snugly around the chest and is resting directly against the
