5. Enstriksyon Enstalasyon

1. Debake: Carefully remove the power supply and all accessories from the packaging. Verify that all components are present (power supply unit, power cord, test leads, user manual).
2. Antre Voltage Seleksyon: Locate the 110V/220V switch on the rear panel. Use a flat-head screwdriver to set the switch to match your local AC power voltage (110V for North America, 220V for most of Europe and Asia). Si ou pa fè sa, ou ka domaje aparèy la.
3. Plasman: Place the power supply on a stable, level surface, ensuring adequate ventilation around the unit. Do not block the fan vents on the rear panel.
4. Koneksyon pouvwa: Connect the provided power cord to the power outlet on the rear panel and then to a grounded AC power outlet.
5. Premye pouvwa sou: Press the instrument power switch on the front panel to turn on the unit. The displays should illuminate.

6. Operasyon Enstriksyon

6.1 Volim Debaztage ak Anviwònman Aktyèl

1. Ensure the power supply is on and no load is connected to the output terminals.
2. Anviwònman Voltage: For CH1 or CH2, press the respective Voltage Adjustment Knob (14 or 7) to activate adjustment. Turn the knob to set the desired voltage. The 4-digit display allows for precise adjustments.
3. Anviwònman aktyèl: For CH1 or CH2, press the respective Current Adjustment Knob (17 or 6) to activate adjustment. Turn the knob to set the desired current limit.
4. Konekte chaj: Apre ou fin mete volim ou vle atage and current, connect your load to the appropriate output terminals (15 for CH1, 12 for CH2, 9 for CH3).
5. Aktive Sòti: Press the CH1 Output Switch (5) or CH2 Output Switch (13) to enable power output to the connected load. The display will show the actual output voltage ak aktyèl.

Note on Output Switch: When enabling output, especially with sensitive loads, there can be a brief current overshoot. It is recommended to set voltage and current limits with the output disabled, connect the load, and then enable the output. For highly sensitive circuits, consider using an external switch or connecting the load after the power supply has stabilized.
