Hand-Grip Heart Rate Sensor Introduction

Introduction
The PASCO Hand-Grip Heart Rate Sensor works with a PASCO interface to collect
heart rate data once every five seconds. The sensor consists of the Heart Rate Sensor
box and the Hand-Grip Assembly. A cable at the end of the Hand-Grips Assembly
connects the Hand-Grips to the front end of the Heart Rate Sensor box.
The Hand-Grips cable extends 2 meters. The Hand-Grips cable is separated about
15 cm originally, but the cable can be separated if needed for about one meter by
gently pulling the hand grips away from each other. A small ‘button’ at the mid-
point of the Hand-Grips cable limits the split distance.
The Hand-Grip Heart Rate Sensor can be used to make measurements during mild
exercise. For example, it can be used to determine the effects of mild exercise on
heart rate. NOTE: the Hand-Grip Heart Rate Sensor is not a medical instrument. It
cannot be used to gauge the health or fitness of a person.
Range
The range of the Hand-Grip Heart Rate Sensor is from 40 to 240 beats per minute.
Theory of Operation
Like an electrocardiograph (EKG) that monitors the electrical signal of the heart, the
Hand-Grip Heart Rate Sensor measures electrical signals that start at the heart and
reach the skin at the palms of the hands.
The sensor box has a yellow light emitting diode (LED) that indicates when the
sensor is in STANDBY mode and a green LED that indicates when the sensor
is ACQUIRING data.
The sensor box has a red LED that flashs to indicate when a heart beat (BEATS) has
been detected.
Maintenance of the Hand-Grips
The Hand-Grips for the Heart Rate Sensor should be wiped clean on a regular basis
with a damp cloth or paper towel. Do not submerge the Hand-Grips in water.
Setup
Hardware Setup
The following three steps can be performed in any order.
1. Connect the mini-DIN plug of the Hand-Grip Assembly to the front end of the
Heart Rate Sensor box.
The mini-DIN plug on the Hand-Grip Assembly fits into the sensor box in only one way.
2. Connect the Hand-Grip Heart Rate Sensor to a PASPORT interface.
3. If you will be using a computer, connect the PASPORT interface to the com-
puter’s USB port.

NOTE: The split distance of
the Hand-Grips cable does
NOT need to be increased,
but it can be increased for
your convenience.
