1:Use P1C16f628a microcontrollers 2degoDo not need batteries, power from the ignition 3: Standard Futaba Plug(Black-negative Red-Postive and White-Signal) 4:Using high-brightness LED digital tube 5:Input voltage range: 3.5V -8.4V 6:Current consumption 25mA-60mA 7:Mini tachometer indicates up to 30000rpm 8:Actual RPM=Display digital *10 9:Body size:41mm L*17mm W*12mm H 10: Window size:30mm L*15mm H 11:Weight: 8.5g(0.3OZ)
Instructions: 1:The Y wiring tandem between in the Hall sensor and the ignition 2: The tachometer plug the other end with Y wire 3:Connected to ignition power supply and can be displayed
Note: That connecting plugs do reinforcement.To preven vibration. the hall sonsor& tachmoter wire leave from the ignition high-voltage wire, And re- ceiver wires over 30cm
Connection tachometer is not recommended after the use of the flight, Best to remove the Y wire to restore the original sensor connection
If ignition have an additional tachometer pinout,You must be connected to dedicated tachometer signal wire
