3. vortex INSTRUCTIONS Inspeed Vortex with Madgetech Pulse Data Loggers Thank you for purchasing an Inspeed Field Logging Kit Here are some things you should know about it Overview The Inspeed Vortex wind sensor produces one pulse per rotation The Madgetech data logger is designed to count the number of pulses during a given time interval Given the pulse rate to wind speed formula which is specific to each rotor type the Madgetech M1 Rotor pre 2005 data logging system produces an output which is AVERAGE WIND SPEED during that interval Use amp Operation The BC1200 display is to provide wind speed information only It is not required for operation NOTE In case of problems reverse the display wires to the logger sometimes there is a polarity conflict that can result in zero readings Check the polarity of the display wires and connect the high to and ground to the red amp black colors mean nothing D2 Rotor current Both the BC1200 and the data logger in the box are VELCRO MOUNTED just pull to remove For example for a time interval of two minutes if one First follow the instructions for the Madgetech data interval contained 240 pulses and we were using the logger to load the software select your appropriate D2 rotor the average speed would be time interval and data logging scheme Note that shorter intervals will produce shorter periods during AWS 240pulses 120sec 2 5 5 mph which the
