Auto ignition probe is an inductive capacitive sensor designed for use with oscilloscopes. It features a BNC connector for oscilloscope connection, a test clip, and a grounding clip for high-voltage signal acquisition. Features: - Inductive capacitive sensor design - High-quality, professional high-voltage ignition probe - Three-terminal configuration: BNC connector for oscilloscope input, signal test clip, and grounding clip - Built-in attenuator for high-voltage signal reduction to protect the oscilloscope from electrical damage Safety Notes: (1) Do not attach test clips directly to spark plugs. Always connect to the insulated portion of the spark plug wire to prevent breakdown and electric shock. (2) Maintain a minimum distance of 2 inches from other high-voltage sources to avoid interference. (3) HT25 model lead length: 2.5 meters; attenuation ratio: up to 10,000:1 Specifications: - Quantity: 1 pc - Length: Approx. 2.45 m (8.0 ft) - Item Weight: 144.2 g (5.1 oz) - Package Size: 24.5 × 17.5 × 3 cm (9.6 × 6.9 × 1.2 in) - Package Weight: 151 g (5.3 oz) Package Includes: - 1 × Auto Ignition Probe - 1 × User Manual
