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. Today 1890s Drum kymograph according to Ludwig The PowerLab and a LabTutor panel, displaying a section of recorded data 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. Data acquisition with a Power Lab system The Power Lab Hardwa re Unit A recordin g 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. T The 4/25T model is a four-channel PowerLab with Bio Amps for optimal 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 con nec ted, the sig nal con diti one rs are 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. EVENT MARKER STIMULATING BAR ELECTRODE FORCE TRANSDUCER CONNECTING YOUR POWERLAB Any number of transducers may be connected to one of the four available inputs.
