Elite Performance & Accurate Detection

This relay tester is engineered to provide a comprehensive "go / no-go" health assessment of the most common automotive relays found in modern cars and heavy-duty vehicles:

• Dual Voltage Compatibility: Supports both 12V and 24V systems, making it suitable for standard passenger cars, SUVs, and commercial trucks.

• Universal 4-Pin & 5-Pin Testing: Features dedicated settings to test both 4-pin (normally open/closed) and 5-pin (changeover) electromagnetic relays.

• Dynamic Cyclic Testing: Automatically cycles the relay 10 times during a single test session to check for consistency and detect intermittent failures that a static multimeter test might miss.

• Contact Load Simulation: Loaded testing detects excessive resistance, burnt contacts, or "pitting" that can cause voltage drops and circuit malfunctions.

Professional Hardware & Smart Diagnostics

• Instant LED Feedback: Uses a simple tri-color LED system (Green for Pass, Red for Fail) to provide immediate visual confirmation of the relay's status.

• Diagnostic Trouble Codes: Advanced models feature flashing LED codes to identify specific failures, such as shorted pins, defective coils, or "welded" contacts.

• Battery-Powered Portability: Many versions operate directly from the vehicle’s battery via insulated alligator clips or use internal 18650 batteries, allowing for convenient off-car testing.

• User-Friendly Design: Equipped with a high-definition display and built-in lighting for efficient operation in dim workshop environments or at night.

Technical Specifications

• Application Range: 12V / 24V Automotive Relays.

• Supported Pin Configurations: 4-Pin and 5-Pin electromagnetic relays.

• Safety Protections: Fully protected transceiver lines and galvanically isolated components to prevent damage to the relay or the tester.

• Dimensions: Approximately 200 x 97 x 27 mm for ergonomic handheld use.
