OBDResource RT100: The Ultimate Flagship Smart Relay Tester
One Tool. Zero Effort. Total Accuracy.
The RT100 represents the pinnacle of automotive relay diagnostic technology. It is not just a tool; it is an intelligent technician in your pocket. Driven by an advanced MCU (Microcontroller Unit), the RT100 eliminates the era of manual switches and clunky battery clamps, making diagnosis faster, safer, and more precise than ever before.
The Flagship Advantage: Why RT100 Redefines the Market
1. Universal All-in-One Socket (Maxi Support)
Total Compatibility: Featuring a revolutionary universal socket design, the RT100 fits Standard, Mini, and Maxi (Large Pin) relays without needing extra adapters or secondary slots.
Heavy-Duty Ready: Specifically engineered with 9.5mm wide-pin openings to handle high-amp Maxi relays used in cooling fans, starters, and ABS systems.
2. Smart Auto-ID Technology
Zero-Configuration Testing: Forget toggling 4-pin or 5-pin switches. The RT100’s intelligent mapping algorithm automatically detects the pin layout for 5 different circuit types (covering over 20+ relay variations).
Dual Voltage Logic: Automatically recognizes and adapts to 12V or 24V systems. No risk of blowing a fuse or damaging the device due to incorrect voltage settings.
3. True Wireless Portability
Dual Power Modes: Powered by 3 x AA batteries for complete wireless freedom or via Type-C cable for continuous bench testing.
Test Anywhere: Whether you are at a salvage yard, in the warehouse, or on a roadside call, you can diagnose relays instantly without dragging heavy jumper cables to a vehicle battery.
4. MCU-Driven Digital Precision
Beyond the "Click": Unlike basic testers that only check for a mechanical click, the RT100 uses MCU-controlled digital sampling to monitor contact resistance and milliohm-level voltage drops.
Intermittent Fault Detection: Its sophisticated diagnostic logic catches "ghost failures"—relays that click but fail under load—ensuring 100% reliable results.
