4. Setup

1. Unpacking: Carefully remove the SPM6103 and all accessories from the packaging. Inspect for any signs of damage.
2. Placement: Place the unit on a stable, level surface with adequate ventilation around the intelligent temperature control fan on the rear panel.
3. Power Connection: Connect the provided power cord to the power cord socket on the rear panel of the SPM6103, then plug the other end into a grounded AC power outlet.
4. Initial Power On: Flip the power switch on the rear panel to the 'ON' position. The LCD display should illuminate, indicating the unit is powered on.

5. Operating Instructions

5.1 DC Power Supply Mode

The SPM6103 functions as a programmable DC power supply with adjustable voltage and current limits.

1. Setting Voltage: Press the Voltage Setting button (1) and use the Adjustment knob (6) to set the desired output voltage.
2. Setting Current Limit: Press the Current setting button (2) and use the Adjustment knob (6) to set the desired output current limit. This acts as a safety feature to prevent overcurrent.
3. Output ON/OFF: Press the Channel output on/off button (7) to enable or disable the power output. The display will indicate the output status. A long press on this button activates the automatic output function.
4. Circuit Protection (OVP/OCP): The device features Over Voltage Protection (OVP) and Over Current Protection (OCP). These can be set via the Over voltage protection, Over current protection button (3) to protect your connected circuit from damage. The intelligent CV/DC switching mode also contributes to effective circuit protection.
5. USB Charging Port: The front USB port (8) provides a 5V/1A output for charging mobile phones or other compatible devices.
