4. Bedienungsanleitung

4.1 Ein-/Ausschalten

• Einschalten: Drücken Sie die Netztaste (red button with power symbol) to turn on the device. The LCD will illuminate.
• Ausschalten: Halten Sie die Netztaste for a few seconds until the display turns off. The device will also automatically shut down after 2 minutes of inactivity.

4.2 Einheitenumrechnung

Drücken Sie die U/S button to cycle through the available torque units: Nm (Newton-meters), kgf.cm (kilogram-force centimeters), lbf.ft (pound-force feet), and lbf.in (pound-force inches). The selected unit will be displayed on the LCD.

4.3 Modusauswahl

Drücken Sie die M-Taste to switch between operating modes:

• Track Mode (Real-time): Displays the current torque value being applied in real-time.
• Spitzenmodus: Captures and displays the maximum torque value achieved during an application.

4.4 Setting Target Torque (Preset Value)

To set a target torque value for the alarm function:

1. Stellen Sie sicher, dass das Gerät eingeschaltet ist.
2. Drücken Sie die U/S button to enter the setting mode. The display will show a flashing value.
3. Verwenden Sie die + Und - buttons to adjust the target torque value.
4. Drücken Sie die M-Taste to confirm the setting and exit the setting mode.

4.5 Torque Application and Alarm Function

Once the target torque is set, apply torque to the fastener using your ratchet wrench with the ENC-340 attached.

• When the applied torque reaches 80 % of the preset value, the red LED indicator will flash, accompanied by an intermittent buzzer alarm.
• When the applied torque continuously reaches 100 % of the preset value, the red LED indicator will turn on steadily, and the buzzer will sound continuously. This indicates that the target torque has been achieved.
