Impostare

Installazione della batteria

The ARM303-4A-340 requires 2 AA batteries (not included) for operation.

1. Locate the battery compartment cover, typically at the base of the handle.
2. Open the cover by twisting or sliding it according to the markings.
3. Inserire 2 batterie AA, assicurandosi che la polarità sia corretta (+ e -) come indicato all'interno del vano.
4. Chiudere saldamente il coperchio del vano batterie.

Accensione iniziale

Press the power button (usually marked 'ON/OFF') to turn on the wrench. The LCD display will illuminate and perform a self-test before showing the current measurement mode.

Istruzioni per l'uso

Accensione/spegnimento

Premere il tasto ACCESO/SPENTO button to power the wrench on or off. The wrench features an auto-shutoff function after approximately 3 minutes of inactivity to conserve battery life.

Selezione unità

Premere il tasto NOI (Unit/Setting) button to cycle through the available measurement units: ft-lbs, in-lbs, N-m, and Kg-cm. Select the desired unit before setting the target torque.

Impostazione della coppia

To set the target torque value:

1. Ensure the wrench is in the desired measurement unit.
2. Premere il tasto M (Mode) button to enter the torque setting mode.
3. Utilizzare il Up E Giù arrow buttons to adjust the target torque value.
4. Premere il tasto M button again to confirm the setting and return to measurement mode.

Measurement Modes (Peak Hold / Track)

The wrench typically offers two measurement modes:

• Modalità traccia: Displays the real-time torque being applied.
• Modalità di mantenimento del picco: Displays the maximum torque value reached during the application.

Cycle between these modes using the appropriate button (refer to the specific button labels on your device, often combined with the 'M' button).

Misurazione dell'angolo

For applications requiring torque-plus-angle (TTY) specifications:

1. Set the desired torque value first.
2. Premere il tasto A-F-K button (or similar) until the angle degree symbol appears on the display.
3. Utilizzare il Up E Giù arrow buttons to set the target angle.
4. Apply torque until the set torque value is reached, then continue rotating until the set angle is achieved. The wrench will provide alerts for both thresholds.

Applicazione della coppia

Attach the appropriate socket to the 1/2" drive head. Place the socket onto the fastener. Apply steady, smooth force to the wrench handle. The LCD display will show the real-time torque. When the set target torque is reached, the wrench will emit an audible beep, flash its LED lights, and vibrate.
