User Interface

3.1 Power on and Run
Before connecting the power supply, make sure that the power supply voltage switch on the rear panel is consistent
with the actual connected voltage, and the frequency is 50Hz or 60Hz.
Note: If the instrument is damaged due to the wrong power supply, it will not be covered by the product
warranty.
Before plugging in the power cord, make sure that the power switch on the front panel is off.
Connect the power cord to the AC power input terminal and the three-hole AC power output terminal on the rear
panel (AC power supply with grounding wire).
Warning: The three-hole power cord that comes with the instrument has an independent grounding terminal. The
power supply used must be three-hole and grounded, otherwise, it may cause electric shock.
Press the power switch to power on the instrument.
3.2 Output Terminals
1. Each channel can be used as an independent channel.
2. When CH1 and CH2 are connected in series or in parallel, pay attention to the wiring method.
3. The green indicator of each channel indicates the constant voltage mode, and the red indicates the constant
current mode.
