N PPS SPORTS MACHINES TENDO Weightlifting Analyzer Version V 207 A microcomputer system for strength diagnostic and feedback monitoring of weight training USER S MANUAL www tendosport com Why use TENDO Weightlifting Analyzer One of the most exciting things going on now in athletics is the use of weight training to improve performance in other sports Weights are used to develop explosive power maximum strength and muscular endurance to correct muscular weakness and imbalance to prevent or rehabilitate injuries and to improve technique and performance in virtually every sport For example a person may have a lot of strength at bench press but not be able to do shot put well He doesnt have the speed of movement that combined with strength generates the necessary power for a long throw Strength in and of itself does not guarantee high performance Power is the most important ingredient in many sports It is an athlete s ability to rapidly develop strength It is a product of strength and velocity of muscular contraction Human muscle is composed of two very general types of fibers fast twitch and slow twitch All people have both fast and slow twitch fibers Fast twitch fibers contract faster and can produce more explosive movements but they fatigue faster You can not change the ratio of fast twitch and slow twitch fibers in your body but weight training can maximize development of those fast twitch fibe2. microcomputer 2 Plug the other end of the VSU Cable into the appropriate connector on your Velocity Sensor Unit TWA V 207 and tighten 2 screws The Velocity Sensor Unit TWA V 207 is used for Weightlifting Analyzer only p A 1 2 Battery Installation Before the microcomputer is operated 4 AA batteries must be installed batteries included Batteries are supplied discharged and must be charged before use charger included Refering to the insert drawing locate the batteries into compartments on the back of the microcomputer Press two batteries into each battery compartment MAKE SURE that the negative ends of the batteries marked are touching the springs marked in the battery compartment Average Power control LED light should be flashed lf a NET Interface option is used it is not necessary to install the batteries The power for microcomputer is supplied from the interface sama Battery compartments If the microcomputer is turn on and the brightness of LED display is lower or in upper display flash sign Lbat law battery power the batteries need to be charged It is possible to use an external power supply with Regulated AC DC Adaptor min 200mA output DC 9 12V polarity in the midpoint of connector Ce Tendo Weightlifting Analyzer Microcomputer Set does not include an External Power Supply Adapter 2 Technical description The system consists of 2
