5. Configuració

5.1 DC Power Supply (SPS-12003) Setup

1. Place the power supply on a stable, level surface with adequate ventilation.
2. Assegureu-vos que l'interruptor d'alimentació (14) estigui en la posició OFF.
3. Connect the provided AC power cord to the AC Power Inlet (16) on the rear of the unit and then to a grounded wall outlet.
4. Connect the red output cable to the Output Terminal + (11) and the black output cable to the Output Terminal - (13). If grounding is required, connect the green cable to the Grounding Terminal (12).
5. Connect the other end of the output cables to your load or circuit, ensuring correct polarity.

5.2 Digital Oscilloscope (JDS210) Setup

1. Place the oscilloscope on a stable, non-slip surface.
2. Connect the provided AC power cord to the power input on the rear of the oscilloscope and then to a grounded wall outlet.
3. Attach the oscilloscope probes to the BNC input connectors (CH1, CH2) on the front panel. Ensure the probe's ground clip is connected to the circuit's ground.
4. Calibrate the probes if necessary, following the instructions in the oscilloscope's on-screen menu or a dedicated probe calibration section (not detailed here, refer to general oscilloscope usage guides).

6. Instruccions de funcionament

6.1 Operating the DC Power Supply (SPS-12003)

1. Encès: Flip the Power Switch (14) to the ON position. The LED display will illuminate.
2. Configuració Voltage: Utilitzeu el voltagManeta (gruixuda) (6) per a ajustos grans i el volumtage Knob (Fine) (8) for precise adjustments. Observe the Voltage Display (1) to set the desired output voltage.
3. Setting Current Limit: Use the Current Knob (Coarse) (7) and Current Knob (Fine) (9) to set the maximum output current. This acts as a safety limit to protect your circuit. Observe the Current Display (2).
4. C.V. and C.C. Modes:
   • Quan la sortida voltage is stable and below the set current limit, the C.V. Mode Indicator (4) will light up, indicating Constant Voltagmode e.
   • If the load draws more current than the set limit, the power supply will automatically switch to Constant Current (C.C.) mode, and the C.C. Mode Indicator (5) will light up. The output voltage will drop to maintain the set current.
5. Port de càrrega USB: The 5V/2A USB Charging Port (10) can be used to charge compatible devices. This port operates independently of the main output voltage/Configuració actual.

Figura 6.1: Illustration of the 5V/2A USB charging port on the Jesverty SPS-12003 DC Power Supply, compatible with various devices.
6. Apagar: Before disconnecting the load, turn the output voltage and current knobs to their minimum settings, then flip the Power Switch (14) to the OFF position.

6.2 Operating the Digital Oscilloscope (JDS210)

1. Encès: Press the power button on the front panel. The display will light up.
2. Connexió de sondes: Connect the probe to the BNC input (CH1 or CH2) and attach the probe tip to the test point and the ground clip to the circuit ground.
3. Classificació automàtica: Press the "Auto" button for automatic adjustment of vertical and horizontal settings to display a stable waveform.
4. Controls verticals: Use the "Vertical" knobs (mV/Div, V/Div) to adjust the vertical scale (voltage per division) and "Position" to shift the waveform vertically.
5. Controls horitzontals: Use the "Horizontal" knobs (ns/Div, s/Div) to adjust the horizontal scale (time per division) and "Position" to shift the waveform horizontally.
6. Activació: Adjust the "Trigger" level to stabilize the waveform display. The trigger ensures the waveform starts at a consistent point on the screen.
7. Mides: Use the "Measure" button to access automatic measurements (e.g., Vpp, Vrms, Frequency, Period). Use the "Cursor" button to enable manual cursors for precise voltage (ΔV) and time (ΔT) measurements.
8. Emmagatzematge USB: Connect a USB drive to the USB port on the side of the oscilloscope to save waveform data or screenshots. Use the "Copy" or "Save" function from the menu.
9. Selecció de canals: Use the CH1 and CH2 buttons to enable or disable channels and access their individual settings.

7. Manteniment

• Neteja: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of both devices. Do not use abrasive cleaners or solvents.
• Ventilació: Ensure the cooling vents on both devices remain clear of obstructions to prevent overheating.
• Emmagatzematge: Store the devices in a cool, dry place away from direct sunlight and excessive dust when not in use.
• Fuse Replacement (SPS-12003): If the power supply does not turn on, check the fuse located in the Fuse Box (17) at the rear. Replace with a fuse of the same type and rating only.
