• 4 Cursor Modes (ΔV, ΔT, ΔV+ΔT, auto-tracking)
• Auto-Ranging for horizontal/vertical adjustments

5. Setup

5.1 DC Power Supply (SPS-12003) Setup

1. Place the power supply on a stable, level surface with adequate ventilation.
2. Ensure the power switch (14) is in the OFF position.
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. Operating Instructions

6.1 Operating the DC Power Supply (SPS-12003)

1. Power On: Flip the Power Switch (14) to the ON position. The LED display will illuminate.
2. Setting Voltage: Use the Voltage Knob (Coarse) (6) for large adjustments and the Voltage 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:
   • When the output voltage is stable and below the set current limit, the C.V. Mode Indicator (4) will light up, indicating Constant Voltage mode.
   • 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. USB Charging Port: The 5V/2A USB Charging Port (10) can be used to charge compatible devices. This port operates independently of the main output voltage/current settings.

6. Power Off: 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. Power On: Press the power button on the front panel. The display will light up.
2. Connecting Probes: 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. Auto-Ranging: Press the "Auto" button for automatic adjustment of vertical and horizontal settings to display a stable waveform.
4. Vertical Controls: Use the "Vertical" knobs (mV/Div, V/Div) to adjust the vertical scale (voltage per division) and "Position" to shift the waveform vertically.
5. Horizontal Controls: Use the "Horizontal" knobs (ns/Div, s/Div) to adjust the horizontal scale (time per division) and "Position" to shift the waveform horizontally.
6. Triggering: Adjust the "Trigger" level to stabilize the waveform display. The trigger ensures the waveform starts at a consistent point on the screen.
7. Measurements: 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. USB Storage: 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. Channel Selection: Use the CH1 and CH2 buttons to enable or disable channels and access their individual settings.

7. Maintenance

• Cleaning: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of both devices. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure the cooling vents on both devices remain clear of obstructions to prevent overheating.
• Storage: 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.
