Steam metal pitch ruler has a charging function, so you don’t need to worry about battery failure during use. It comes with a Type-C charging cable to provide power to the product at any time. It is suitable for measuring the angle of helicopter rotors with a blade root thickness of 5mm/8mm/10mm/12mm/14mm .
First, place the metal pitch ruler on a relatively flat part of the motor or helicopter, and short-press the ABS/REF button to reset the angle to zero. Then install the metal pitch ruler on the rotor to obtain the angle value, which is the pitch angle.
Button description:
1. ON/OFF button, for turning on / off the device. (Press and hold for three seconds) The device will display the default horizontal angle when turned on.
2. ABS/REF key. Short press the key to return the value to zero and the LCD display will show (REF) 0.0 °. Short press the key again and the LCD display ( ABS ) will show the initial horizontal angle.
