INTRODUCTION TO THE POWER LAB AND LAB TUTOR
THE POWER LAB SYSTEM
The Power Lab System is basically used to record various Physiological
activities of humans and animals for which the signal or data analysis and
manipulation become very much easy and less time consuming.
The technology derives from equipment such as
the kymograph and paper chart-recorders.


Power Lab Converts signals of mechanical and Physiological
activities into amplified electrical Signal by different devices.
 These Devices are called as Transducer which receive signal, amplify it and
transmit it towards the Computer.
LAB TUTOR
 A Software is installed to run the Power lab hardware known as Lab tutor.
 It is an HTML-based software package, designed specifically for laboratory
work and used in conjunction with ADInstruments' PowerLab.
 LabTutor controls all work of hardware such as, sampling and storage of
experimental data, and allows you to display, manipulate and analyze them.

instrument that measures electrical signals, through the inputs on its front panel. It
can also generate voltage pulses for electrical stimulation of nerve and muscle.

recording of biological signals
Signal Conditioners
 AD Instruments signal conditioners are software-controlled pre-amplifiers
for use with Power Lab data acquisition systems.
 The two types you are likely to see are Pods and Front-ends. Once

automatically identified by the Power Lab system, and all settings are stored
when the data file is saved on your computer.
ACCESSORIES
Signal Transducers
 Transducer generates an analog voltage between ±10V may be attached to
the PowerLab. Either directly or through any signal conditioners.
