1. Connect the positive terminal of the DC power supply to the red thin wire メーターの。
2. Connect the negative terminal of the DC power supply to the black thin wire メーターの。
3. Connect the positive terminal of the load to the red thick wire メーターの。
4. Connect the negative terminal of the load to one end of the external shunt.
5. Connect the other end of the external shunt to the black thick wire メーターの。
6. Ensure all connections are secure and correct before applying power. Incorrect wiring can damage the product.

重要： The load cannot exceed the rated voltage and current of the meter (DC 6.5-100V, 100A). This device is designed for indoor use only.

操作手順

Once properly wired and powered on, the meter will display voltage, current, power, and energy readings on its LCD screen. The device has a single button for various functions.

ボタンの機能:

• ショートプレス: バックライトのオン/オフを切り替えます。
• 長押し（3秒）： Resets the energy (kWh) accumulation. The energy value will flash, then release the button. Press again to confirm reset, or long press again to cancel.
• 設定ボリュームtage アラームしきい値:
  1. Press and hold the button for 6 seconds until the voltage value flashes.
  2. Short press to adjust the alarm voltage value. The value will increase by 0.5V with each press.
  3. Long press for 3 seconds to save the setting and exit.

The meter will automatically store data when power is removed, ensuring that accumulated energy readings are not lost.

メンテナンス

The KETOTEK KT-D138 is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• クリーニング： 柔らかく乾いた布を使用してディスプレイとcを清掃してください。asing. 研磨剤入りの洗剤や溶剤は使用しないでください。
• 環境： Operate the device in a dry, indoor environment. Avoid exposure to moisture, extreme temperatures, and direct sunlight.
• 接続: Periodically check all wiring connections to ensure they remain secure. Loose connections can lead to inaccurate readings or device malfunction.
• ストレージ： When not in use for extended periods, store the meter in a cool, dry place.
