Follow these steps to set up your DC power supply:

• ማሸግ፡ የኃይል አቅርቦቱን እና ሁሉንም መለዋወጫዎች ከማሸጊያው በጥንቃቄ ያስወግዱ። የጉዳት ምልክቶችን ይፈትሹ።
• አቀማመጥ፡- Place the unit on a stable, level surface with sufficient space for ventilation. Avoid placing it near heat sources or in direct sunlight.
• የኃይል ግንኙነት; Ensure the power switch is in the 'OFF' position. Connect the provided AC power cord to the power input socket on the rear of the unit and then to a grounded AC power outlet.
• የመለዋወጫ ፍተሻ፡- Confirm all included accessories are present, such as the power cord and output test leads.

5.1. የመጀመሪያ የኃይል ማብራት እና ማስተካከያ

1. Ensure no load is connected to the output terminals.
2. Turn the power switch to 'ON'. The digital display will illuminate.
3. ቅንብር ጥራዝtagሠ (ቋሚ ጥራዝtagሠ ሁነታ፡
   • 'VOL'ን አዙርTAGE COARSE' knob clockwise to increase the voltage or counter-clockwise to decrease it.
   • 'VOL'ን ይጠቀሙTAGE FINE' knob for precise adjustments to reach the desired voltage.
   • The CV indicator LED should be lit, indicating Constant Voltagሠ ሁነታ።
4. Setting Current Limit (Constant Current Mode):
   • Rotate the 'CURRENT COARSE' knob fully counter-clockwise to set the current limit to its minimum.
   • Short-circuit the output terminals (connect positive to negative with a test lead). The CC indicator LED should light up.
   • Rotate the 'CURRENT COARSE' and 'CURRENT FINE' knobs clockwise to set the desired current limit. The display will show the set current.
   • Remove the short circuit. The CC indicator will turn off, and the CV indicator will light up again. The current display will show '0.00A'.

5.2. Connecting a Load

1. Ensure the power supply is off or the output voltage is set to zero before connecting your load.
2. Connect the positive (+) terminal of the load to the red (+) output terminal of the power supply.
3. Connect the negative (-) terminal of the load to the black (-) output terminal of the power supply.
4. If grounding is required for your application, connect the green (GND) terminal to the appropriate ground point on your circuit.
5. Turn on the power supply and slowly adjust the voltage and current to the desired levels. Observe the load's behavior.

5.3. Understanding CV/CC Modes

• የማያቋርጥ ጥራዝtage (CV) Mode: When the load resistance is high enough that the current drawn is less than the set current limit, the power supply operates in CV mode. The output voltage remains constant at the set value, and the current varies according to the load. The CV indicator LED will be lit.
• Constant Current (CC) Mode: When the load resistance is low enough that the current drawn attempts to exceed the set current limit, the power supply automatically switches to CC mode. The output current remains constant at the set limit, and the output voltage drops to maintain this current. The CC indicator LED will be lit.

6. ጥገና

Proper maintenance ensures the longevity and reliable operation of your power supply:

• ማጽዳት፡ Disconnect the power supply from the AC outlet. Use a soft, dry cloth to clean the exterior. Do not use abrasive cleaners or solvents.
• የአየር ማናፈሻ; Regularly check that the ventilation openings are free from dust and obstructions. Use compressed air to clear dust if necessary.
• ማከማቻ፡ When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and excessive humidity.
• የኬብል ምርመራ; Periodically inspect the power cord and test leads for any signs of damage (fraying, cuts). Replace damaged cables immediately.
