Kuasa Awal Hidup

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.

Arahan Operasi

Hidupkan/Mati Kuasa

Tekan ke HIDUP/MATI 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.

Pemilihan Unit

Tekan ke A/S (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.

Tetapan Tork

To set the target torque value:

1. Ensure the wrench is in the desired measurement unit.
2. Tekan ke M (Mode) button to enter the torque setting mode.
3. Gunakan Up dan Bawah arrow buttons to adjust the target torque value.
4. Tekan ke M button again to confirm the setting and return to measurement mode.

Measurement Modes (Peak Hold / Track)

The wrench typically offers two measurement modes:

• Mod Trek: Displays the real-time torque being applied.
• Mod Tahan Puncak: 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).

Pengukuran Sudut

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

1. Set the desired torque value first.
2. Tekan ke A-F-K button (or similar) until the angle degree symbol appears on the display.
3. Gunakan Up dan Bawah 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.

Memohon Tork

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.
