Nastavení
Instalace baterie
The ARM303-4A-340 requires 2 AA batteries (not included) for operation.
- Vyhledejte kryt přihrádky na baterie, obvykle na spodní straně rukojeti.
- Open the cover by twisting or sliding it according to the markings.
- Vložte 2 baterie typu AA a dbejte na správnou polaritu (+ a -) vyznačenou uvnitř přihrádky.
- Bezpečně zavřete kryt bateriového prostoru.
Počáteční zapnutí
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.
Návod k obsluze
Zapnutí/vypnutí
Stiskněte tlačítko 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.
Výběr jednotky
Stiskněte tlačítko NÁS (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.
Nastavení točivého momentu
To set the target torque value:
- Ensure the wrench is in the desired measurement unit.
- Stiskněte tlačítko M (Mode) button to enter the torque setting mode.
- Použijte Up a Dolů arrow buttons to adjust the target torque value.
- Stiskněte tlačítko M button again to confirm the setting and return to measurement mode.
Measurement Modes (Peak Hold / Track)
The wrench typically offers two measurement modes:
- Režim stopy: Displays the real-time torque being applied.
- Režim Peak Hold: 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).
Měření úhlu
For applications requiring torque-plus-angle (TTY) specifications:
- Set the desired torque value first.
- Stiskněte tlačítko A-F-K button (or similar) until the angle degree symbol appears on the display.
- Použijte Up a Dolů arrow buttons to set the target angle.
- 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.
Použití krouticího momentu
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.
