4. Grounding: Connect the ground wire to the grounding terminal for safety.
5. Power On: Flip the power switch on the rear panel to the 'ON' position. The device display will illuminate.

4. Operating Instructions

4.1 Power Supply Operation

The SPM6103 functions as a variable DC power supply. Use the voltage and current adjustment knobs to set the desired output parameters.

Figure 4.1: DC Power Supply Interface. This image illustrates the main display for the DC power supply, showing actual output power, cumulative running time, channel output status (ON/OFF), actual voltage and current output, and the set/limit values for voltage and current.

• Voltage Setting: Turn the 'Voltage' knob to adjust the output voltage.
• Current Setting: Turn the 'Current' knob to adjust the output current limit.
• Output ON/OFF: Press the 'On/Off' button to enable or disable the power output.
• Constant Voltage (CV) / Constant Current (CC) Mode: The device automatically switches between CV and CC modes based on the load and set limits.
• USB Output: The 5V/1A USB port can be used to charge mobile devices.

4.2 Multimeter Operation

The integrated 4 1/2 digit multimeter allows for various electrical measurements.

4.5 Protection Features

The SPM6103 incorporates multiple protection mechanisms to safeguard the device and connected circuits.

Figure 4.5: Protection Features. This image highlights the independent output On/Off button control and the ability to set overvoltage (OVP) and overcurrent (OCP) values to protect the circuit. It also explains Constant Voltage (CV) and Constant Current (CC) output modes.

• Over-Voltage Protection (OVP): Prevents output voltage from exceeding a set limit.
• Over-Current Protection (OCP): Prevents output current from exceeding a set limit.
• Short-Circuit Protection: Automatically shuts down output in case of a short circuit.
• Thermal Protection: Protects the device from overheating.

5. Maintenance and Care

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure the ventilation openings on the sides and rear of the device are clear of obstructions to prevent overheating.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Fuse Replacement: If the device does not power on, check and replace the fuse located near the power cord socket on the rear panel. Always use a fuse of the correct rating.

6. Troubleshooting

If you encounter issues with your OWON SPM6103, refer to the following common troubleshooting steps:

• No Power: Check the power cord connection, ensure the power switch is ON, and verify the fuse.
• No Output Voltage/Current: Ensure the output is enabled (On/Off button), check the set voltage/current limits, and verify connections to the load.
• Incorrect Readings: Ensure multimeter leads are correctly connected for the desired measurement type and that the correct mode is selected.
• Overload/Protection Triggered: Reduce the load or adjust voltage/current limits. Check for short circuits in the connected circuit.
