4. Installation
4.1. DC Power Supply SPS-3010 Setup
- Déballage: Carefully remove the power supply from its packaging and inspect for any damage.
- Placement: Place the power supply on a stable, level surface with adequate ventilation around the cooling fan (15).
- Connexion électrique : Connect the provided AC power cord to the AC Power Inlet (16) on the rear panel and then to a grounded wall outlet.
- Mise à la terre : Ensure the grounding terminal (12) is properly connected to an earth ground for safety.
- Mise sous tension initiale : Flip the Power Switch (14) to the 'ON' position. The displays should illuminate.
4.2. Digital Multimeter HK33D Setup
- Installation de la batterie : Open the battery compartment on the back of the multimeter and insert the required batteries, observing polarity.
- Connexion du fil de test : Insert the red test lead into the "VΩmA" or "10A" jack (depending on measurement) and the black test lead into the "COM" jack.
- Mise sous tension : Rotate the function dial from "OFF" to the desired measurement function.
5. Mode d'emploi
5.1. Operating the SPS-3010 DC Power Supply
- Volume de réglagetage:
- Tournez le Voltage Knob (Coarse) (6) to set the approximate desired voltage.
- Utilisez le volumetage Knob (Fine) (8) for precise adjustments.
- Observe the Voltage Display (1) for the output voltage.
- Définition de la limite de courant :
- Turn the Current Knob (Coarse) (7) to set the approximate desired current limit.
- Use the Current Knob (Fine) (9) for precise adjustments.
- The Current Display (2) shows the actual output current or the set limit when no load is connected.
- Connexion de la charge :
- Connect the positive lead of your load to the Output Terminal + (Red) (11).
- Connect the negative lead of your load to the Output Terminal - (Black) (13).
- Ensure connections are secure before applying power to the load.
- C.V. and C.C. Mode:
- L'alimentation bascule automatiquement entre le volume constant et le volume continu.tage (C.V.) and Constant Current (C.C.) modes.
- When the load resistance is high, the unit operates in C.V. mode (C.V. indicator (4) illuminates).
- When the load resistance is low and the current reaches the set limit, the unit switches to C.C. mode (C.C. indicator (5) illuminates), maintaining the set current.
- Port de charge USB: The 5V/2A USB Charging Port (10) can be used to power or charge compatible USB devices.
