{"product_id":"3-channel-servo-tester","title":"3 Channel Digital Servo Tester for RC Models and ESC Speed Controller","description":"\u003cp\u003eThe 3 Channel Digital Servo Tester is an essential tool for RC hobbyists, offering a precise and efficient way to test and calibrate servos and electronic speed controllers (ESCs). This compact device allows you to easily detect and adjust common issues such as servo jitter, dummy bits, and median positions.\u003c\/p\u003e\n\u003cp\u003eWith the ability to connect up to three servos or ESCs simultaneously, this tester provides high stability and accuracy, thanks to its MCU control. It features three distinct operating modes—Manual, Neutral, and Automatic—making it versatile for various testing needs.\u003c\/p\u003e\n\u003cp\u003eThis tester is particularly useful for controlling electronic governors (both brushed and brushless), eliminating the need for a remote control and receiver during testing. By simply turning the adjustment knob, you can manually control the speed and performance of your motor, acting as a \"manual receiver.\"\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e This tester is not suitable for servos weighing more than 55 grams.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eKey Features and Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCompact Design:\u003c\/b\u003e Lightweight (8g) and small in size (46 x 32 x 17mm) for easy portability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThree Adjustment Modes:\u003c\/b\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eManual Mode (Man):\u003c\/b\u003e Use the adjustment knob to precisely control the servo position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNeutral Mode (Neutral):\u003c\/b\u003e Fixes the servo at the central angle (median position).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAutomatic Mode (Auto):\u003c\/b\u003e Automatically cycles the servo through its full range of motion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh Accuracy and Stability:\u003c\/b\u003e Controlled by an MCU for reliable results.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVersatile Input:\u003c\/b\u003e Requires DC 4.2V-6.0V input (ensure sufficient current and thick wires for proper function).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOutput Signal:\u003c\/b\u003e 1.5ms ± 0.5ms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eConnectors:\u003c\/b\u003e Three sets of output pins (Positive, Negative, Signal) for simultaneous connection of up to 3 servos or ESCs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eConnect your power source (DC 4.8V-6V) to the \"IN\" pins, ensuring correct polarity (Positive and Negative).\u003c\/li\u003e\n\u003cli\u003eConnect the servo(s) or ESC(s) to the \"OUT\" pins.\u003c\/li\u003e\n\u003cli\u003eUse the \"Select\" button to switch between Manual, Neutral, and Automatic modes.
