5. 操作手順

5.1 電源オン/オフ

• オンにするには： 力 ボタン。
• オフにするには： 力 button for approximately 3 seconds. The device will also auto shut off after 70 seconds of inactivity.

5.2ユニットの選択

The adapter supports torque units in Newton-meters (Nm), foot-pounds (lb-ft), and kilogram-meters (kg-m).

• To change units: Simultaneously press the P / T そして M buttons. The unit displayed on the screen will cycle through Nm, lb-ft, and kg-m. Release the buttons when the desired unit is shown.

5.3 目標トルク値の設定

1. を押す M button to enter the preset torque setting mode.
2. 使用 '+' そして 「-」 buttons to adjust the target torque value. Pressing and holding these buttons will increase or decrease the value more rapidly.
3. Once the desired value is set, press the M もう一度ボタンを押して確定し、設定モードを終了します。

5.4 Torque Application and Alerts

Attach the digital torque adapter to your 1/4 inch drive ratchet wrench, then attach the appropriate socket to the adapter's output drive. Apply torque to the fastener.

図5.1: Adapter in Use. The image shows the digital torque adapter connected to a ratchet wrench, being used to tighten a fastener on an engine.

• As you apply torque, the digital display will show the real-time torque value.
• When the applied torque reaches 80% of the preset target value, the buzzer will begin to sound, and the LED will flash. The frequency of the beeps and flashes will increase as the torque approaches the target.
• When the preset target torque value is reached, the buzzer will emit a continuous tone, and the LED will flash rapidly. At this point, stop applying force immediately to avoid over-tightening.

5.5 Peak Hold (P) and Track (T) Modes

• トラックモード（T）： Displays the real-time torque value as it is being applied. This is the default mode.
• ピークホールドモード（P）： Displays the maximum torque value achieved during the tightening process. To switch to Peak Hold mode, press the P / T button once. The display will show 'P' to indicate Peak Hold mode. To clear the peak value, press the P / T もう一度ボタンを押します。

6. メンテナンス

6.1 クリーニング
