7. User s Manual altimeter v1 1 Optimal Tracking 01 15 15 a i The altimeter is completely autonomous It can be installed on any model It automatically detects the beginning of flights and does not record the period between two consecutive flights which allows you to store a large quantity of flights The essential parameters of the last flight recorded can be displayed directly on the altimeter screen From the observation of the glide over a short period the altimeter estimates what would be the flight duration without dethermalizing The entire log can be transferred to a PC for more detailed study The purpose of the altimeter is to measure the performance of models on short duration flights and display it instantly It allows methodical and quick adjustment of models 1 Overview of the altimeter Screen Male connector JST ZM 03 Display button Configuration button 2 Necessary equipment e Female connector JST ZH 03 o Itis available on the Optimal Tracking site e USB cable specific to the altimeter o Itis available on the Optimal Tracking site o Itis only useful for connection to a PC e Battery o The altimeter can be supplied by any battery or rechargeable battery with voltage of 2 5 to 6 volts that can deliver a peak of 35mA The ideal is to connect the altimeter to a lithium battery A battery of 5 0mAh allows several days of autonomy If the model already has a lithium battery connect to it
