Simple Intelligent Auto-Detection

The probe automatically recognizes DC voltage, polarity, resistance, and continuity upon contact—no need to manually switch modes.

Data Hold Function: Press the "Hold" button to lock readings on screen for easy recording and troubleshooting.

Wide-Range Multifunctional Testing

Broad Voltage Range: Supports 0.8V–100V DC testing—ideal for fuse checks, wiring diagnostics, battery analysis, and ACC system inspections.

Automatic Polarity Detection: Instantly identifies positive/negative terminals; a "-" symbol indicates negative polarity.

Precision Resistance & Continuity: Measures resistance from 1Ω to 20MΩ with high resolution (0.001Ω under 2V, 0.1V at 100V). Accuracy rated at ±1%.

Safety & Precision Design

Real-Time Alerts: Built-in buzzer triggers an alarm when resistance drops below 50Ω. Screen shows "OL" for voltages exceeding 100V.

Safe Operation: Long spring negative clip and protective probe head cover prevent short circuits and enable one-handed use.

User-Friendly Features

Backlit LCD & Flashlight: Clear visibility in dim environments with built-in backlight and LED flashlight.

Auto Power-Off: Shuts down after 15 minutes of inactivity to conserve battery life.

Portable Storage: Includes a compact storage bag for safe transport and organized use.
