Setup and Installation

The HM058B offers flexible installation options and requires connection to the engine for RPM and hour tracking.

1. Engine Signal Connection

To measure RPM and track engine hours, the device must be connected to the engine's spark plug wire. Wrap the signal wire around the spark plug wire as shown in the diagram. Ensure a secure connection for accurate readings.

2. Product Installation

The HM058B can be installed using two primary methods:

• Stick-on Mounting: Use the provided double-sided adhesive tape to secure the meter to a clean, flat surface.
• Screw-on Mounting: Utilize screws to firmly attach the meter to a desired location.

Operating Instructions

Clock Function

When the engine is off, the device displays the current time in a 24-hour format. This allows for convenient timekeeping without engine operation.

Tachometer (RPM) Function

When the engine is running, the HM058B automatically displays the real-time engine RPM. This feature is crucial for monitoring engine performance and ensuring operation within safe limits.

Service Timers (SVC & SVC2)

The device includes two programmable service timers (SVC and SVC2) that count down to a set maintenance interval. These are ideal for reminding users of scheduled maintenance tasks such as air filter replacement.

Job Timers (JOB & JOB2)

Two resettable job timers (JOB and JOB2) are available to measure the duration of specific work tasks. These can be reset to zero for each new task, such as an oil change or a particular project.

Maximum RPM Recording

The HM058B records and can display the maximum RPM achieved during engine operation. This allows users to review peak engine speeds.

Programmable RPM Alert

Users can set a programmable RPM alert. When the engine RPM exceeds this set value, the display backlight will turn red, and a warning symbol will flash, indicating an over-RPM condition.

Programmable Firing Patterns

The HM058B can be programmed to match various engine ignition patterns, ensuring accurate RPM readings across different types of gasoline engines. This includes setting the RPM measurement range and refresh rate for improved data accuracy.

Initial Time Setting

The total hour meter (TOT) range is 0-999999 hours with 0.1-hour accuracy. Users can set an initial total hour value, which is useful when replacing an existing hour meter to maintain continuous tracking of engine hours.

Display Backlight

The display features a programmable backlight that can be set to green or turned off. In alert conditions (e.g., SVC reminder or RPM alert), the backlight automatically changes to red to draw immediate attention.

Maintenance

Service Reminders

The programmable SVC and SVC2 timers will alert you when scheduled maintenance is due. Ensure these timers are set appropriately for your equipment's service intervals.

Battery Replacement

The HM058B is powered by a replaceable CR2450 lithium metal battery. The device will indicate when the battery level is low, prompting replacement. Data is retained even during battery replacement.

Troubleshooting

If you encounter issues with your Runleader HM058B, consider the following general troubleshooting steps:

• No Display/Power: Check if the battery is correctly installed and has sufficient charge. Replace the CR2450 battery if necessary.
• Inaccurate RPM Readings: Ensure the signal wire is securely wrapped around the spark plug wire. Verify that the programmable firing pattern setting matches your engine type.
• Hour Meter Not Advancing: Confirm the engine signal connection is secure. The hour meter only advances when the engine is running and detected.
• Display Malfunction: If the display is frozen or showing incorrect characters, try removing and reinserting the battery to perform a soft reset.
• Water Ingress: Although rated IP67 waterproof, ensure the device is properly sealed and not subjected to extreme water pressure or prolonged submersion beyond its rating.

For persistent issues, refer to the detailed instructions included with your product or contact customer support.
