1. ເອົາແຫຼ່ງຈ່າຍໄຟອອກຈາກການຫຸ້ມຫໍ່ຢ່າງລະມັດລະວັງ.
2. Inspect the device for any signs of physical damage. If damage is found, do not operate the unit and contact your supplier.
3. Ensure all accessories (e.g., power cord, test leads) are present.

4.2 ການຈັດວາງ

• ວາງແຫຼ່ງຈ່າຍໄຟໄວ້ເທິງພື້ນຜິວທີ່ໝັ້ນຄົງ ແລະ ຮາບພຽງ.
• Ensure adequate ventilation around the unit. Do not block the air vents on the sides and rear.
• Keep the device away from direct sunlight, heat sources, and excessive dust or moisture.

4.3 ການເຊື່ອມຕໍ່ພະລັງງານ

1. Ensure the power switch on the front panel is in the "OFF" position.
2. Connect the provided AC power cord to the power input socket on the rear panel.
3. Plug the other end of the power cord into a suitable grounded AC power outlet (230V AC, 50Hz).

5. ຄໍາແນະນໍາການດໍາເນີນງານ

5.1 Basic Operation (Output A and C)

1. ເປີດ: Flip the power switch to the "ON" position. The displays will illuminate.
2. ການຕັ້ງຄ່າລະດັບສຽງລ່ວງໜ້າtage ແລະປັດຈຸບັນ:
   • Before connecting your load, turn the voltage adjustment knobs (coarse and fine) to set the desired output voltage.
   • Adjust the current adjustment knobs (coarse and fine) to set the maximum current limit. This acts as a protection mechanism for your circuit.
3. ການ​ເຊື່ອມ​ຕໍ່​ການ​ໂຫຼດ​: Connect the positive (+) terminal of your load to the red output terminal and the negative (-) terminal of your load to the black output terminal.
4. ການຕິດຕາມ: The displays will show the actual output voltage and current being supplied to your load.
5. Overvoltage ການປົກປ້ອງ (OVP): The OVP function protects the connected load from excessive voltage. Adjust the OVP knob to set the maximum permissible voltagຈ. ຖ້າຜົນຜະລິດ voltage exceeds this limit, the power supply will shut down the output.
