Safety Approvals CSA Certified, TUV Product Service licensed, UL EMI Regulation Complies with FCC Part 15, Class B, VDE 0871B, Vfg. 2431991 Inductive Pickup Input: Magnetic field from spark plug Output: Pulse to trigger Fluke 78 Thermocouple Type: K (Chromel vs. Alumel) (Fluke 80PK1) Not suitable for immersion in liquid. Accuracy: ±1.1°C (2°F) between 0°C to 260°C (32°F-500°F). Typically within 1.1°C (2°F) of NBS tables for temperatures between 40°C (40°F) to 0°C (32°F). Temperature Range: 40°C to 260°C. (40°F to 500°F). Above 260°C (500°F), toxic gas might be emitted. NOTE: The temperature range is primarily a function of the thermal limitations of the thermocouple's insulation. Cable Insulation: Teflon MIN MAX Recording Accuracy: Specified accuracy of measurement function ±16 digits for changes > 200 ms in duration (±52 digits in 400 J). Nominal response time (5 to 100% of range) 100 ms to 80%
