HJ Digital Servo Tester - ESC
The HJ Digital Servo Tester / ESC Tester is a compact electronic device used for testing and calibrating RC servos and ESC (Electronic Speed Controllers). It can test up to 4 servos simultaneously, allowing comparison of performance and synchronization accuracy. The tester generates precise PWM control signals with a resolution up to 2 microseconds, enabling fine control and response checking. It supports manual, neutral, and automatic modes, and can simulate different signal frequencies for analog and digital servos. This makes it ideal for robotics, RC models, and electronics development.

The HJ Digital Servo Tester / ESC Tester is a multifunctional diagnostic tool designed for testing, calibrating, and analyzing the performance of RC servos and Electronic Speed Controllers (ESCs). It is widely used in robotics, remote-controlled vehicles, drones, and electronic prototyping.
The device is capable of testing up to four servos simultaneously, allowing users to evaluate synchronization and compare response performance between multiple servo motors. It generates precise PWM control signals with high resolution, capable of detecting very small changes in pulse width (up to 2 microseconds accuracy), ensuring accurate servo response testing.
It supports PPM signal input testing, where it can monitor incoming PPM signals and synchronize output to connected servos. The device automatically enters manual mode when powered on, allowing direct control of pulse width using a rotary potentiometer.
The tester includes multiple operating modes, including manual, neutral, and automatic cycling modes, making it suitable for a wide range of servo testing scenarios. It also supports different signal frequencies suitable for both analog and digital servos.
