1. Highway Information Systems _ OPERATIONS MANUAL Portable Traffic Analyzer NC300 This manual is provided for reference purposes and as a quick guide for users that are somewhat familiar with the equipment If you are a first time user or have not yet installed the necessary Highway Data Management HDM Software on your computer please do so at this time M H Corbin Inc All rights reserved Follow the instructions on the CD provided for installation of software 1 0 INTRODUCTION M H Corbin Portable Traffic Analyzer NC300 is a self contained vehicle detector that requires no external D sensors M H Corbin s a m NC300 is installed under a protective cover in the center of the traffic lane so that motor vehicles pass over the counter No physical contact by a vehicle is necessary M H Corbin s Traffic Analyzer uses Vehicle Magnetic Imaging VMI to detect vehicles as they move through a magnetic field Every motor vehicle has parts that are constructed from iron When a vehicle passes over the NC300 Traffic Analyzer the iron parts interfere with the magnetic field This disturbance creates electrical signal changes in the NC300 Traffic Analyzer sensors As a result the NC300 Traffic Analyzer can determine vehicle presence count each vehicle measure vehicle speed and record vehicle length The NC300 also reports road surface temperature 2 0 BATTERY CHARGING AND CARE The maximum length of a2. d customer service representative DO NOT soak or wipe with solvents such as paint thinner turpentine kerosene etc To prevent damage to the housing follow the recommended Installation and Removal procedures refer to HDM manual for details The electrical pins used are designed to withstand extreme environmental conditions Since they are open sockets occasional cleaning may be required using tap water and a small brush to wash away any dirt that may have lodged in the cavities DO NOT force any sharp objects into the sockets since this may damage the pin retention ring The NC300 should never be stored in a metal area or container that would allow contact with the electrical connector pins This could result in the unintentional shorting of the power ON pin which may deplete the battery or interrupt a planned study 10 0 ERROR MESSAGES amp TROUBLESHOOTING Refer to the electronic manual provided on the HDM CD for detailed information 11 0 Technical Support and Product Returns For technical questions or product returns contact M H Corbin at 1 800 380 1718 Provide the following supporting information and request either service or product return e Name and model of the product in question e Serial number of the product e Name and location of the installation site e Name and contact information of a technically competent person who can provide further information on the problem
