PS100Pro Automotive Circuit Tester & Short Finder

All-in-One Diagnostic Solution for 12V & 24V Vehicles

Meet All Your Automotive Circuit Needs

This advanced circuit tester integrates eight core functions into a single device, eliminating the need for multiple tools. Ideal for maintenance, servicing, and troubleshooting across all scenarios.

  • ✅ Voltage Testing
  • ✅ Component Activation
  • ✅ Polarity Testing (+/-)
  • ✅ Current Waveform
  • ✅ Resistance & Diode
  • ✅ Continuity & Frequency

Whether checking battery voltage, activating starters, fuel pumps, and headlights, or troubleshooting complex circuits, this tool handles it all efficiently.

High Compatibility & Extended Reach

Designed for flexibility with two power supply methods: direct connection to an external/car battery or via the cigarette lighter to prevent power interruptions.

  • Extended Cables: Includes a 6-meter main test cable and a 6-meter extension cable.
  • Hard-to-Reach Areas: Easily access deep engine compartments or under-chassis components without moving the device or vehicle frequently.
  • Voltage Range: Input 8V~32V; Testing range 0V~80V. Compatible with 12V passenger cars and 24V trucks/construction machinery.

Dual Safety Protection

Built for safety with overload and reverse connection protection.

  • Auto-Trip: Automatically trips if activation current exceeds 8A (resettable by restarting).
  • Reverse Polarity: Prevents damage from incorrect battery terminal connections.
  • Ideal for beginners and professionals alike, reducing operational risks.

High-Definition Display & Indicators

Equipped with a 1.8-inch TFT color screen for clear visualization of key data including voltage, resistance, frequency, duty cycle, and real-time Max/Min values.

  • Multimodal Alerts: Features a buzzer and dual-color (Red/Green) LED indicators.
  • Visual Logic: Red LED + Beep indicates positive terminal; Continuous beep + Red LED indicates continuity.
  • Built-in LED Light: Illuminates dark work environments for better visibility.

User-Friendly Operation

Intuitive toggle switch design with smart controls:

  • Single Click: Switch interfaces or enter tests.
  • Double Click: Lock current display for easy data comparison.
  • Long Press: Rotate screen 180° to adapt to different testing angles.
  • Safety Prompt: Displays "Do not test under power" before resistance testing.
  • Languages: Supports 12 languages for global users.
