CCPM Servo Consistency Master / Servo testerThe device also can be used as a signal generator for electric speed controller (ESC), then you can test your motor system without using a transmitter and receiver.There are 3 modes to check servos or ESC:Manual mode: turn the knob with different speed, check the reaction time.Neutral mode: make the servo go back to the neutral point.Automatic "window wiper" mode: make the servo swing like a window wipers in the biggest angle.It can connect 1-3 servos simultaneously and test such as 1-3 servos consistency and so on.You can also connect 1-3 ESC to test and compare their reaction time respectively.It can connect 3 servos of the CCPM helicopters and select servos.It can also connect the servo of airplanes install the steering-box and adjust planes by using such as the neutral mode and so on.Voltage consumption: DC4.8-6VSize: 48 x 42 x 17mmWeight: 31.5 g Output: 15mA (5.0)Input: DC 4.5 ~ 6VNeutral point output signal: 1.5ms 0.5msSize: 42.5 x 24.0 x 23.5mmWeight: 8gPulse width adjustment mode: automatic / manual adjustment / automatic neutral point signal outputSpecifications:built-in BEC or UBEC3 Pulse width adjustment mode15mA OutputDC 4.5 ~ 6V Input1.5ms0.5ms Neutral point output signaleasily detect the clearance, jitter and median of all kinds of Servo This RC CellMeter-8 digital battery capacity checker is able to be used for LiPo LiFe Li-ion NiMH Nicd batteries.Features:Support Battery Type:LiPo, LiFe, Li-ion, NiCd, NiMHServo Test Mode:Manual adjustment, Auto Matic, NeutralServo Test Frequency: 50Hz, 60Hz, 100Hz, 125Hz, 200Hz, 250Hz, 300HzDisplay Mode: Battery cell voltages, Total Voltages, Lowest cell voltage, Highest cell voltage, Voltage gap between highest cell voltage and Lowest cell voltage, Remaining battery capacity(%).Specifications:Item size: 8.5 * 5 * 1.6cmItem Weight: 40gPackage size: 10.5 * 10 * 2cmPackage Weight: 55g Material: Plastic Color: Black Size:7.5 cm x 3.8 cm x 2.5 cm Weight: 0.88 ounce (30 g) Input voltage: DC 5~6V Output signal width: 800~2200u Can be synchronized output control 4 servos and used to compare the performance steering gear control of the steering servo output signal can be accurate to 2us (1 milliseconds = 1000 microseconds), you can test the steering gear is able to respond to subtle change With PPM signal test function in the display, the input PPM signal changes while the input the PPM signal synchronization output to the servo Energized automatically enter manual mode (Manual) 20u 50H analog servo signal cycle, frequency 50Hz, rotary potentiometers to decrease or increase the width of the output pulse Button the Select (Note: the key switch function, circulation patterns) 1.
