Digital LED Servo Tester

This portable device allows you to test the functionality of your servos and ESC without having to connect your radio, receiver and battery. Servos testers also allow you to easily center your servos when attaching servo horns and making control surface adjustments. This time-saving tool is a must have tool for any RC enthusiast.

Testing frequency is adjustable for analog and digital servos with input voltage of 4.8 to 6 volts and output signal width: 800~2200us.

Features:

• 4-digit LED displays pulse width in real-time
• Synchronized output control allows performance comparison of 1-4 servos connected simultaneously.
• Servo output signal accuracy up to 2us (1 milliseconds = 1000 microseconds), to allow testing precise changes in the servo response.
• Digital display shows the input PPM signal and the PPM signal synchronization output to the servo.
• 50H analog servo signal cycle, frequency 50Hz, rotary potentiometers allow width of the output pulse to be decreased or increased.
• Select Button provides 3 different modes:

S-1 Manual adjustment mode (Manual)--to check the servo speed and reaction time

S-2 Bit mode (Neutral)

S-3 Automatic mode (Automatic)--test the servo through its full travel from end-point to end-point (like windshield wipers)

• Pulse Width is selectable with a Button:

1. 50H analog servo signal cycle 20us frequency 50H

2. 125H digital the steering gear a signal cycle 8us frequency 125Hz

3. 250H digital Servo signal cycle 4us frequency 250Hz
