Setup and Installation
1. Battery Activation
The device comes with a pre-installed CR2032 battery. Before first use, locate the battery compartment on the back of the meter. Remove the insulating sheet to activate the battery. Ensure the battery is correctly seated before closing the compartment.
Figure 3: Battery activation by removing the insulating sheet.
2. Mounting the Meter
The meter can be mounted using either the provided double-sided tape (stick-on) or screws (screw-on).
- Stick-on Mounting: Clean the desired mounting surface thoroughly. Apply the double-sided tape to the back of the meter and firmly press the meter onto the surface.
- Screw-on Mounting: Use the provided bolts, nuts, and washers to secure the meter to a suitable location. Ensure the mounting is stable and does not interfere with engine operation.
Figure 4: Mounting options for the meter.
3. Engine Signal Pickup (Tachometer)
Connect the signal pickup wire to the spark plug cable. Wrap the signal wire 5-8 times around the spark plug cable. This allows the meter to detect engine RPM.
Figure 5: Signal wire connection for RPM measurement.
4. Temperature Sensor Installation
Attach the TS002 probe sensor to the engine nut or another suitable metal surface where temperature measurement is desired. Ensure good contact for accurate readings. The internal dimension of the temp sensor is 14mm.

Operating Instructions
1. Power On/Off
The meter automatically powers on when the engine starts or when the insulating sheet is removed from the battery. To turn off the meter, press and hold the 'M' and 'S' buttons simultaneously for approximately 2 seconds until the display shows "OFF".
2. Display Modes
Press the 'M' button to cycle through different display modes:
- Real-time Temperature: Displays the current engine temperature.
- Maximum Temperature: Shows the highest temperature recorded during operation.
- Real-time RPM: Displays the engine's revolutions per minute when the engine is running.
- Total Hours (TOT): Shows the total accumulated operating hours of the engine.
- Partial Hours (JOB): Displays the operating hours for a single working period, which can be reset.
- Service Timer (SVC): Shows the countdown for scheduled maintenance.

3. Setting Alerts and Backlight
Use the 'S' button to enter settings mode. Follow the on-screen prompts to set temperature alerts, RPM alerts, and adjust backlight modes (sleeping, always on, always off). The red backlight will activate when an alert condition is met or maintenance is due.

Maintenance
1. Service Interval Reminder
The meter features a Service (SVC) timer that can be set to remind you of regular maintenance tasks. When the countdown reaches zero, the red backlight will illuminate, indicating that service is due.

2. Battery Replacement
When the battery indicator shows low power, replace the CR2032 battery. Open the battery compartment on the back of the meter, remove the old battery, and insert a new CR2032 battery with the positive (+) side facing up. Close the compartment securely.
3. Cleaning
Clean the meter's display and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents. The device is IP67 waterproof, allowing for exposure to water, but avoid prolonged submersion or high-pressure jets directly on the display.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | Battery not activated or depleted. | Remove insulating sheet from battery or replace battery. |
| Inaccurate RPM reading | Signal wire not wrapped correctly or insufficient turns. | Ensure signal wire is wrapped 5-8 times tightly around the spark plug cable. Adjust RPM accuracy settings if available (refer to detailed manual for specific steps). |
| Inaccurate Temperature reading | Temperature sensor not making good contact or improperly installed. | Check sensor placement and ensure firm contact with the engine surface. |
| Red backlight constantly on | Temperature or RPM alert threshold exceeded, or service interval due. | Check engine conditions (temperature, RPM) or reset the service timer. Adjust alert thresholds if necessary. |
