Features
1. Can test the control of 4 servos at the same time
2. Accurate testing: The output signal of the servo control servos used for performance comparison can be accurate to 2us (1ms = 1000 microseconds), allowing testing whether the servos can react to subtle changes.
3. PPM signal: A PPM signal test function is available. On the display, the input PPM signal changes while the input PPM signal is synchronised to the servo power-up and automatically enters manual mode (20us 50h) to simulate the servo signal cycle with a frequency of 50 Hz
4. adjustable: rotating the potentiometer reduces or increases the width of the output pulse
5. 3 modes: S-1 manual / s-2 bit / S-3 automatic
Specification
Input voltage: DC4.8-6V
Output signal width: 800-2200us
Key selection (note: key switch function, cyclic mode)
1. S-1 Manual mode (Manual)
2. S-2-bit mode (Neutral)
3. Auto S-3 mode (Auto)
Pulse width keys.
