1. Tachometer Wiring: Wrap the signal wire (typically black) around the spark plug wire of your engine. The number of wraps can affect sensitivity; typically 5-7 wraps are sufficient. Secure with cable ties.
2. Installazione del sensore di temperatura: The TS002 probe sensor should be installed in a location that accurately measures engine temperature. The sensor has a φ14mm (0.55 inches) aperture. Ensure a secure connection.

4.3 Engine Firing Pattern Settings

To ensure accurate RPM readings, configure the meter according to your engine's firing pattern. Refer to the table below:

• JOB (Timer di lavoro): Displays the partial operating hours for a specific task (0-99999 H). This can be reset for individual jobs like oil changes.
• RPM (giri al minuto): Displays real-time engine RPM (0-25000 RPM) when the engine is running.
• Temperatura: Displays the current engine temperature (-20℃ to +300℃ / -4℉ to +572℉).
• SVC (Promemoria di servizio): Displays the countdown to the next scheduled maintenance.

5.2 Impostazione dei parametri

To enter setting mode, press and hold the 'M' button for a few seconds. Use 'M' to navigate through settings and 'S' to adjust values.
