EKG Sensor
PS-2111
*012-088007
Included Parts
1. EKG Sensor
2. Electrode patches, 100 pieces
Additional Part Required
• PASPORT interface or datalogger
Quick Start
1. Connect the EKG Sensor to your PASPORT interface.
2. If you are using a computer, connect the PASPORT interface
to it and start DataStudio.
3. Apply three electrode patches to the subject’s arms and clip
the leads to the electrodes patches as illustrated in Figure 1.
4. Press or click the start button to begin recording data.
Introduction
The EKG Sensor measures electrical signals produced by the
heart. The EKG trace, displayed on a connected computer or dat-
alogger, graphically illustrates the beating of the heart.
Set-up
Connecting the EKG Sensor to an Interface
1. Connect the sensor’s plug to any port of a PASPORT inter-
face or datalogger. Optionally, use a PASPORT extension
cable (PS-2500) between the interface and the EKG Sensor.
2. If you are using a computer, connect the PASPORT interface
to it and start DataStudio.
Connecting the EKG Sensor to a Person
1. Rub the skin where the electrode
patches will be applied with a
paper towel to remove dead skin
and oil.
2. Apply adhesive electrode
patches to the right wrist, right
forearm just below the elbow,
and left forearm just below the
elbow (Figure 1). Press the
patches firmly for best adhesion
and signal quality.
3. Clip the EKG leads to the elec-
trode patches: black to the right
wrist, green to the right forearm, and red to the left forearm.
4. Arrange the leads so that they hang loosely without straining
the patches.
Collecting Data
1. Press or click the start button to begin recording data.
2. Have subject remain still during data collection.
About the Measurements
The sensor makes two measurements: Heart Rate (in beats per
minute) and Voltage (in mV). These measurements are recorded
and displayed by the computer or datalogger connected to the
sensor.
