3.2 Engine Signal Connection

The meter connects to your engine via a spark plug wire winding and a temperature sensor probe.

1. RPM Signal: Wrap the provided wire around the spark plug wire of your engine. The meter detects RPM by sensing the ignition pulses. The wire length is approximately 68.8 inches.
2. Temperature Sensor: Connect the TS002 temperature sensor probe to the designated port on the meter. Install the probe in a location that accurately measures engine temperature. Caution: The induction probe cannot be bent to prevent breakage.

The meter is compatible with various gasoline engine types:

• 2-stroke engines: 1, 2, or 3 cylinders
• 4-stroke engines: 1, 2, 3, 4, 5, 6, 8, 12, or 16 cylinders
• 6-stroke engines: 2 cylinders

4. Operating Instructions

4.1 Display Functions

The meter's display provides multiple readings:

• TOT Hours: Total accumulated engine running time (0-999.99 hours).
• JOB Hours: Resettable individual working hours.
• Real-time RPM: Current engine revolutions per minute (0-25000 RPM).
• Current Temperature: Real-time engine temperature (-20 °C to +300 °C / -4 °F to +572 °F).
• SVC Timer: Maintenance reminder countdown (5-1000 hours).

4.2 Backlight Settings

The meter features a green backlight for low-light conditions. The backlight mode can be configured as:

• Always On: Backlight remains continuously active.
• Off: Backlight is disabled.
• Automatic: (Default OFF) The backlight activates when a button is pressed and turns off after a period of inactivity.

A red backlight will activate to indicate an engine RPM or temperature exceed alert.

4.3 Anti-Noise Function

The meter includes an anti-noise interference function to ensure accurate and stable readings, especially in electromagnetically noisy environments. This function can be toggled on or off as needed.

4.4 Initial Hour Programming (INT)

If replacing an existing hour meter, you can program previous engine hours (INT) into the new meter to maintain an accurate total running time. Refer to the detailed programming instructions in the full manual for this procedure.

4.5 Unit Switching

The temperature display can be easily switched between Celsius (°C) and Fahrenheit (°F) units.

4.6 Power Off

To manually turn off the display and conserve battery, press the 'M' button once, then immediately press both 'M' and 'S' buttons simultaneously. 'OFF' will appear on the display. The meter will automatically turn on when the engine starts.

5. Maintenance

5.1 Maintenance Reminders (SVC)

The SVC timer allows you to set recommended maintenance intervals (5-1000 hours). The meter will provide a reminder when the due time approaches, assisting in timely engine servicing.

5.2 Alerts

The meter provides visual alerts for critical engine conditions:

• RPM Exceed Alert: A red backlight and specific display indication will warn if the engine RPM exceeds the set threshold (100-25000 RPM).
• Temperature Exceed Alert: A red backlight and specific display indication will warn if the engine temperature exceeds the set threshold.

6. Troubleshooting

If you encounter issues with your Runleader meter, consider the following common problems and solutions:

• Meter does not turn off: To manually turn off the display, press the 'M' button once, then immediately press both 'M' and 'S' buttons simultaneously. 'OFF' will appear on the display. The meter is designed to automatically turn on when the engine starts.
• Incorrect RPM readings: Ensure the RPM signal wire is correctly wrapped around the spark plug wire. Verify that the engine type (2-stroke, 4-stroke, number of cylinders) is correctly configured in the meter's settings. Incorrect settings can lead to inaccurate RPM display.
• Incorrect or fluctuating temperature readings: Check the connection of the temperature sensor probe. A false contact in the plug can cause intermittent disconnections and error signals. Ensure the probe is securely installed and not bent.
• Difficulty with programming functions: The programming interface can be complex. Refer to the detailed programming section in the complete user manual for precise button press sequences and function selection. Ensure you understand the steps before attempting complex configurations, especially for alarms.
• Battery drains quickly: Ensure the meter is properly turned off when not in use if you wish to conserve battery life. Refer to the 'Power Off' instruction in section 4.6.
