Chainsaw Digital Tachometer – Precision Engine RPM Measurement Tool Designed for accurate RPM measurement on 18 cylinder engines, this handheld digital tachometer is ideal for both professional and hobbyist applications. Compatible with 2stroke and 4stroke gasoline or fuel engines, it offers a wide measurement range of 100 to 30000 RPM with an accuracy of ±1%, ensuring reliable performance and improved engine safety. Key Features and Benefits: • Wide Compatibility – Works with 18 cylinder engines in both 2stroke and 4stroke configurations. Suitable for chainsaws, motorcycles, lawnmowers, ATVs, outboard motors, and other gasolinepowered equipment. • Accuracy – Measures engine speed with ±1% precision, helping you monitor performance, conduct tuning, and prevent mechanical issues. • Broad RPM Range – Capable of readings from 100 to 30000 RPM, covering a wide variety of engine types and operating conditions. • Timing Function – Records and displays operating time from 1 to 99999 minutes, allowing you to track usage for maintenance scheduling and engine reliability. • Inductive Design – Uses safe, noncontact measurement via spark plug wire sensing, with a secure metal clip or electronic harness for easy attachment. • Clear LCD Display – Provides easytoread measurements in various lighting conditions. • Portable and Handheld – Compact design with builtin battery power, making it convenient for onsite work. • Zero and Reset Function – Simple reset procedure to clear stored run time and RPM data for fresh measurement cycles. • Multiple Measurement Methods – 1. Clipon method: attach metal clip to spark plug wire housing. 2. Wrap method: wrap electronic harness around spark plug wire sleeve. 3. Proximity method: hold device 35 cm from spark plug wire sheath. • Energy Saving – Automatically powers off when the engine stops to extend battery life; automatically reactivates when engine operation resumes. Applications: 1. Chainsaw Maintenance – Use to measure exact RPMs during tuning or to ensure cutting performance. 2. Motorcycle Engine Diagnostics – Accurately test and adjust idle or maximum RPM during servicing. 3. Lawn Equipment Servicing – Monitor and adjust RPM in mowers, trimmers, or leaf blowers to maintain efficiency, prevent wear, and improve safety.
