Sefdrert Z90 Electronic Pitch Ruler Helicopter Digital Pitch Gauge for 250 450 500 600 700 RC

Explain Applicable blade width: 20mm~75mm. Angle measurement range: +90 degrees. Measurement resolution: 0.1 degree. Working voltage: 3.0V/DC. Current consumption: 3mA. Working temperature: 0-40 ℃. Resolution: 0.1 ° Product Description: This product consists of pitch calipers and sensors, which are adsorbed together by magnets on the back of the sensor. After removing the sensor, it can support the main rotor with a maximum of 700 mm stuck, which is convenient for use in 250,380,450,500,600,700,90 oil helicopters and 700 electric helicopters. The maximum measurable degree of positive and negative inductors is 90 degrees and the resolution is 0.1 degrees. Product Specification Characteristics: Built-in digital gyroscope to detect rotor angle. Backlight LCD is used. Possessing angle zero and locking function. Detectable angle range (+90 degrees). Have the function of automatic screen inversion. Applicable to 250-700 mm main rotor. Built-in power saving function turn off power automatically after 3 minutes standby. Body size: 108x53.7x16mm 1. 0N/0F - On/Off. 2. HOLD key - angle lock. 3. ZERO key - reset to zero. 4. Place the instrument on a horizontal table, the ZERO button, and the LCD display show 0.0 ° when the value returns to zero. At this point, the measured angle value is the relative horizontal angle value, Manufacturer: Sefdrert
