Specification

Feature

• Dual-button Control: The hand held engine tachometer with hour meter adopts a dual-function button design for intuitive and convenient operation, enabling quick settings and mode switching. 
• High-Accuracy Data Capture: A built-in digital signal processing system ensures precise and stable RPM readings with minimal error. 
• Wrap-around Inductive Sensing: The portable tachometer allows non-invasive measurement by simply wrapping the sensor wire a few turns around the spark plug, delivering real-time RPM signals with ease and broad compatibility. 
• Smart Screen and Backlight Adjustment: An LCD display supports automatic screen-off during standby to conserve power. Users can select screen modes (Auto: S-Aut / Always-on: S-ON) and three backlight modes (Auto: L-Aut / Always-on: L-ON / Always Off: L-OFF). 
• Durable and Protective Design: The handheld engine RPM meter offers excellent water and shock resistance, certified IP65, making it reliable for outdoor and high-vibration environments. 
• Upgraded Power System: Powered by a high-capacity CR2450 coin cell (DC 3V) for extended runtime. 
• Intelligent Timing and Maintenance Reminder: Hour recording, from 0 to 99999 hours, allows custom maintenance intervals. When the set time is reached, “SERVICE” flashes on the display as a reminder. 
• Professional RPM Measurement: The handheld engine RPM gauge continuously detects ignition signals and displays real-time engine speed on the main screen, covering a range of 0–30000 rpm with selectable 2-stroke or 4-stroke gasoline engine modes. 
• Wide Compatibility: Suitable for all gasoline engines equipped with spark plugs, including off-road motorcycles, ATVs, hedge trimmers, lawn mowers, chainsaws, and similar outdoor power equipment.

Tips: How does the hand held engine tachometer with hour meter work?

1. RPM Measurement: The hand held engine tachometer detects the engine's rotational speed (RPM) using a sensor. The sensor is typically attached to the engine's ignition system or another rotating part and generates electrical pulses, which the tachometer counts over time to calculate the RPM. The device displays the calculated RPM on the screen.
2. Hour Meter Function: In addition to RPM measurement, the engine RPM meter tracks the operating hours of the engine. This is done by counting the time the engine is running. The hour meter is powered by the engine’s electrical system and activates whenever the engine operates.
3. Quartz Technology: The portable tachometer uses quartz technology, which is likely used for timekeeping. The use of quartz ensures that the hour meter's readings remain accurate.
4. Installation Instructions: The installation guide suggests mounting the sensor on the ignition coil or another engine part and making sure the sensor's wire wraps around the ignition coil at least 5 times. This helps to stabilize the signal and ensure more accurate readings.
5. Buttons (S1, S2): The S1 and S2 buttons are likely used for resetting the hour meter or switching between different modes (such as calibrating or adjusting settings).
