Înființat

Instalarea bateriei

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. Introduceți 2 baterii AA, asigurându-vă că polaritatea este corectă (+ și -), așa cum este indicat în interiorul compartimentului.
4. Închideți bine capacul compartimentului bateriei.

Pornirea inițială

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.

Instrucțiuni de operare

Pornire/Oprire

Apăsați tasta ON/OFF 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.

Selectarea unității

Apăsați tasta NE (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.

Setarea cuplului

To set the target torque value:

1. Ensure the wrench is in the desired measurement unit.
2. Apăsați tasta M (Mode) button to enter the torque setting mode.
3. Utilizați Up şi Jos butoanele săgeată pentru a regla valoarea țintă a cuplului.
4. Apăsați tasta M button again to confirm the setting and return to measurement mode.

Measurement Modes (Peak Hold / Track)

The wrench typically offers two measurement modes:

• Modul de urmărire: Displays the real-time torque being applied.
• Mod de menținere a vârfului: 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).

Măsurarea unghiului

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

1. Set the desired torque value first.
2. Apăsați tasta A-F-K button (or similar) until the angle degree symbol appears on the display.
3. Utilizați Up şi Jos 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.

Aplicarea cuplului

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.
