• Audio Tone Indicator – Provides menu scrolling assistance, allowing hands-free operation once the user becomes familiar with audio prompts.

• Long Cable for Accessibility – The 20ft (extendable) cable ensures you can test circuits anywhere in the vehicle without repositioning.

• Easy to Use and Highly Reliable – Designed for professional and home mechanics, making electrical diagnostics simpler and faster.

The PS100 features four different modes that help diagnose electrical circuits quickly and accurately:

1. DC Voltage Mode

   • Displays real-time DC voltage readings on the screen with 0.1V resolution.

   • Ensures accurate power delivery to components.

2. AC Voltage Mode

   • Shows maximum and minimum voltage, frequency, and duty cycle for AC circuits.

   • Useful for testing alternators, sensors, and complex electrical signals.

3. Resistance Mode

   • Measures circuit resistance by contacting the probe tip to the component.

   • Helps identify faulty wires, poor connections, and broken circuits.

4. Tone On/Off Mode

   • Provides audible feedback for circuit status, allowing hands-free operation.

   • Ideal for use in bright conditions where LED indicators may be hard to see.

   • The tone can be switched off for long-duration testing.

• Display: TFT Color Display (160 x 128 dpi)

• Operating Temperature: 0 to 60°C (32 to 140°F)

• Power Source: 12V or 24V from the vehicle battery

• Dimensions: 126mm x 46.5mm x 35mm (4.96" x 1.83" x 1.38")

• Weight: Lightweight for easy handling
