3. Press 'M' again to enter the value adjustment. Use the Up/Down arrow buttons to set the desired torque value.
4. Press 'M' to confirm and save the preset.

4. Data Storage & Recall

The wrench can store up to 400 sets of torque data. To recall stored data, press the 'M' button until 'M000' appears on the display. Use the Up/Down arrow buttons to navigate through the stored data sets.

5. Suppression de données

Pour supprimer les données enregistrées :

1. Enter the data recall mode ('M000').
2. Press the 'C' button. The display will show 'ONE' or 'ALL'.
3. Use the Up/Down arrow buttons to select whether to delete a single record ('ONE') or all records ('ALL').
4. Press 'C' to confirm deletion. The display will show 'SUCC' upon successful deletion.

6. Using the Wrench for Tightening

Attach the appropriate socket or adapter to the 3/8" drive head. Place the socket onto the fastener. Apply steady force to tighten the fastener. The LCD display will show the real-time torque. The dual alarm system (LED lights and buzzer) will provide visual and audible feedback as you approach and reach the target torque:

• 80% of Target Torque: Green LED light illuminates, slow beep.
• 90% of Target Torque: Yellow LED light illuminates, fast beep.
• 100% of Target Torque: Red LED light illuminates, long continuous beep.

Stop applying force immediately when the red light and long beep indicate 100% of the target torque has been reached to prevent over-tightening.
