Key Physical Characteristics

• Dimensions: 260 mm (length) × 157 mm (width) × 55 mm (height)
• Color: Vibrant Red, making it easy to spot in a cluttered garage or workshop.
• Build Quality: Rugged housing that resists impact and protects the internal circuitry during field use.

Core Functionalities

The PP1 Auto Probe combines several essential measurement functions into one device, eliminating the need for multiple separate meters.

• Voltage Measurement: Accurately reads DC voltage across a wide range (6 V–24 V). Ideal for checking battery health, alternator output, and accessory power supplies.
• Current Measurement: Measures current flow in circuits up to 12 A. Useful for diagnosing charging system issues or verifying load currents.
• Continuity Testing: Provides a quick check of circuit integrity with audible beep or visual indicator when a complete path is detected.
• Resistance Measurement: Allows you to verify component values and detect shorted or open circuits.

Design Features for Ease of Use

The probe’s ergonomic design ensures comfortable handling during prolonged diagnostic sessions.

• Large, Backlit Display: Clear readouts even in low‑light conditions. The backlight can be toggled to conserve battery life.
• Auto‑Range Switching: Automatically selects the appropriate measurement range, reducing user error and speeding up diagnostics.
• One‑Button Operation: A single button cycles through voltage, current, continuity, and resistance modes. No need for complex menu navigation.
• Durable Probe Tip: The tip is engineered to withstand repeated contact with automotive terminals without degrading performance.

Applications in Automotive Work

The Sealey PP1 Auto Probe excels across a variety of tasks that require reliable electrical measurements.

• Battery and Charging System Checks: Verify battery voltage, alternator output, and regulator function with precise DC readings.
• Accessory Diagnostics: Test power distribution to lights, infotainment systems, and aftermarket accessories for proper operation.
• Wiring Harness Inspection: Use continuity mode to trace broken or damaged wires quickly.
• Component Verification: Measure resistance of resistors, diodes, and other components directly in the circuit.
• High‑Current Circuit Testing: Monitor current draw during engine start-up or accessory load tests to ensure circuits are within safe limits.
