Introduction
The PASCO CI-6539A EKG (Electrocardiogram) Sensor measures
cardiac electrical potential wave forms (voltages produced by the
heart as its chambers contract). The sensor is designed for use with a
PASCO computer interface as an educational aid; it is not intended for
medical diagnosis.
This sensor complements the PASCO CI-6535 Respiration Rate
Sensor.
The sensor consists of the electronics box with a cable for connecting
to the PASCO computer interface via a five pin DIN analog connector.
Three electrode leads enter the electronics box on the side opposite the
cable that attaches to the interface. The sensor’s circuitry isolates the
user from the possibility of electrical shock in two ways.
• The sensor signal is transmitted through an opto-isolation circuit.
• Power for the sensor is transferred through an isolation transformer.
The circuitry protects against accidental overvoltages of up to 4,000
volts.
The sensor comes with a package of one hundred silver/silver
chloride electrode patches that can be attached to the skin.
