5. セットアップ

5.1 バッテリーの充電

Before first use, ensure the device is fully charged. Connect the charger to the device's charging port and plug it into a power outlet. The battery status indicator on the display will show the charging progress.

5.2 Connecting the Impact Device

Carefully connect the standard D impact device cable to the designated port on the AMT212. Ensure a secure connection. The device will automatically identify the connected impact device type.

5.3 プリンタ用紙のセット

Open the printer cover located at the top of the device. Insert a roll of 58mm thermal paper, ensuring the paper feeds correctly through the mechanism. Close the cover securely.

6. 操作手順

6.1 電源のオン/オフ

電源ボタン (通常は電源記号が付いています) を長押しして、デバイスの電源をオンまたはオフにします。

6.2メニューナビゲーション

The AMT212 features a menu-driven interface. Use the arrow keys (Up, Down, Left, Right) and the 'MENU' or 'OK' button to navigate through options and confirm selections. The true color TFT screen provides rich and intuitive information.

6.3 Selecting Material and Hardness Scale

From the main menu, select the appropriate material type (e.g., Steel, Cast Iron, Aluminum Alloy) and the desired hardness scale (e.g., HL, HRC, HB). The device allows for arbitrary switching between materials and hardness scales.

6.4 測定の実行

Ensure the surface of the test piece is clean, smooth, and free from scale, oil, or other contaminants.
Place the impact device firmly and perpendicularly on the test surface.
Press the release button on the impact device to initiate the impact. The measurement will be displayed on the screen.
Repeat the measurement multiple times (typically 3-5 times) at different points on the test piece to ensure accuracy and consistency.
The device can be used at any angle, including upside down, in narrow spaces, or other challenging working conditions.

6.5 Saving and Printing Results

Use the 'SAVE' button to store measurement data in the device's memory. The 'PRINT' button will immediately print the current test results via the built-in printer. The 'FEED' button advances the paper.

6.6 Automatic Alarm Function

The device features an automatic alarm function suitable for batch testing. If a test result falls outside pre-set tolerance limits, the device will automatically alert the user.
