4. 操作手順
4.1 レーザー距離測定
This mode allows for precise distance measurements up to 400ft (120m) with an accuracy of ±1/16 inch.
- 活性化: を押す Power ON/Measure レーザーをアクティブにするボタン。
- 測定: レーザーを目標地点に向け、 Power ON/Measure もう一度ボタンを押すと測定が始まります。測定結果は画面に表示されます。
- 参照ポイント: The device supports measurements from three reference points: front, rear, or screw-hole. Use the Benchmark/Mode switch ボタンをクリックして、これらのオプションを切り替えます。

4.2 Green Cross Line Laser Level Mode
The integrated green cross-line laser provides horizontal and vertical lines for leveling and alignment tasks, with a working distance of up to 33ft (10m) and an angle accuracy of ±1°.
- 活性化: を押す Laser Level Mode button to project the green cross lines.
- レベル調整: Place the device on a stable surface. The screen displays angles from -90° to +90° horizontally. If the angle exceeds ±4°, the 'Out' icon will flash, and the laser line will flash rapidly, indicating it is out of level.
- 三脚マウント: For enhanced stability and precise positioning, the device features a 1/4"-20 tripod mount.

巻尺4.3本
A traditional 6.5ft (2m) physical tape measure is integrated for short-distance measurements or when a laser is not suitable.
- 使用法: Pull out the tape measure from the side of the device. Ensure it retracts smoothly after use.
4.4 測定モードと機能
The SW-T120 supports various measurement calculations:
- 距離測定: Single distance measurement.
- 面積測定: 表面の面積を計算します。
- 容積測定: 空間の体積を計算します。
- Indirect Height (Pythagoras): Calculates height using two or three measurements.
- 連続測定: デバイスが移動すると、リアルタイムの距離更新が提供されます。
- 加算/減算: 測定値を追加または減算できます。
