5. セットアップとバッテリーの取り付け

5.1 バッテリーの取り付け

1. デバイスの背面にある電池ボックスのカバーを見つけます。
2. カバーをスライドさせるか、ねじを外して開きます。
3. Insert four 1.5V LR6 (AA) batteries, ensuring correct polarity (+/-).
4. 電池カバーをしっかりと閉じてください。

5.2 Applying Reflective Tape

For accurate non-contact measurement, apply a piece of reflective tape to the rotating object whose speed or count you wish to measure. Ensure the tape is clean and securely attached.

6. 操作手順

6.1 電源オン/オフ

を押す HOLD / ON/OFF button to turn the tachometer on or off.

6.2 RPM Measurement

1. Ensure the device is in RPM measurement mode (indicated on the LCD). If not, press the ラジコン 切り替えるボタン。
2. Point the laser beam at the reflective tape on the rotating object.
3. Maintain a measurement distance between 50mm and 200mm (2 to 8 inches) from the target.
4. The RPM reading will be displayed on the LCD.
5. 注記： If no signal is detected within 7 seconds, the LCD will display "0.0000". If the RPM exceeds 99999, the LCD will display "OL" (Overload).

6.3 Counts Measurement

1. を押す ラジコン button to switch to Count measurement mode.
2. Point the laser beam at the reflective tape on the object.
3. The device will count the number of times the laser beam reflects off the tape.

6.4 Mode Selection (MAX/MIN/AVG)

を押す まあ ボタンを繰り返し押すと、次の表示モードが切り替わります。

• MAX： 最大の測定値を表示します。
• 分: 最小測定値を表示します。
• AVG： Displays the average measured value.
• 普通： Displays the current real-time measurement.

6.5データ保持

During measurement, a short press of the HOLD / ON/OFF button will freeze the current reading on the display. Press it again to release the data hold and resume live measurement.

6.6年ampリングレート調整

Sampling rate can be adjusted from 0.5 to 255 seconds. Refer to the detailed user manual for specific steps on how to access and change this setting via the メニュー そして チューニング ボタン。
