RC Digital Servo Tester 7 Channels, ESC Consistency Tester w/LCD

About this item

• High Precision Digital LCD Screen: Clear digital LCD screen shows pulse width accurate to 1μs, real-time PWM signal readout for instant servo performance inspection. (Note: Use the button to switch between digital and analog signal modes before connecting to your steering servo, effectively preventing servo damage.)
• 7 Independent Output Channels & Wide Compatibility: 7-channel design tests multiple servos together for consistency comparison; 4.8-6V input, fits all standard analog/digital servos & ESCs for RC planes, cars, helicopters, robotic arms.
• 3 Practical Test Modes: Manual control (adjust pulse width via knob), neutral point setting & automatic sweep modes. Auto swing mode drives servos full stroke to check response speed and dead zones without remote transmitters.
• Easy Operation & Anti-Damage Protection: Two shortcut buttons for quick mode & parameter switching; built-in anti-reverse wiring protection avoids device burnout. Compact lightweight body easy to store in RC tool bags for field use.
• Practical RC Servo Debug Tool: No transmitter required for pre-install servo testing. Ideal for center calibration, troubleshooting unresponsive servos, and sync-matching multi-servo systems like helicopter swashplates.
