5.3 Connecting Load

Use the provided test leads to connect your load to the output terminals. Ensure correct polarity (red for positive, black for negative). For CH1 and CH2, use the corresponding output terminals. CH3 (fixed 5V) also has dedicated output terminals.

6. Operasyon Enstriksyon

6.1 Front Panel Overview

The front panel provides all necessary controls and displays for operating the power supply.

• CH1 V, A display: Digital displays for Voltage and Current of Channel 1.
• CH2 V, A display: Digital displays for Voltage and Current of Channel 2.
• CH1 Adjustment knob: Encoder knob for setting Voltage and Current for Channel 1. Push to switch between coarse/fine adjustment.
• CH2 Adjustment knob: Encoder knob for setting Voltage and Current for Channel 2. Push to switch between coarse/fine adjustment.
• Endikatè mòd: Lights indicating CC (Constant Current) or CV (Constant Voltage) mode.
