The 3CH Servo Tester CCPM Consistency Master Checker is a compact testing tool designed for checking and controlling RC servo motors and electronic speed controllers (ESCs) without requiring a transmitter or receiver. With three servo output channels, the tester can operate multiple servos simultaneously, making it useful for checking servo movement, comparing servo consistency, centering servo horns and setting up CCPM systems. It supports common RC servos operating from approximately 4.8V to 6V DC. The tester provides multiple operating modes for manual position adjustment, automatic sweeping and neutral/center positioning. An onboard rotary control allows easy adjustment of the servo position, while the indicator lights provide visual feedback during operation.
