   Warning：
   To prevent electric shock, make sure that the instrument is properly grounded.

2. Press the power button on the front panel, the button light will be on, and the startup screen will be displayed on the screen.

3.4 Output Inspection
Output inspection is to ensure that the instrument can achieve its rated outputs and properly respond to operation from the front panel. For the procedures below, it is suggested that you read “Turn On/Off the Channel Output” on page 8 and “Set the Output Voltage/Current” on page 8.

3.4.1 Voltage Output Inspection
The following steps verify basic voltage functions without load:

1. When the instrument is under no load, select a channel and ensure the output current setting for this channel is not at zero.
2. Turn on the channel output, then ensure the channel is in Constant Voltage output mode.
3. Set some different voltage values on this channel; check if the actual voltage value displayed is close to the set voltage value, and also that the actual current value displayed is nearly to zero.
4. Check that if the output voltage can be adjusted from zero to the maximum rating, When it is set to the maximum or minimum, a beep is heard, indicating that the limit has been reached.

3.4.2 Current Output Inspection
The following steps check basic current functions with a short across the power supply’s output:

1. Connect a short across (+) and (-) output terminals with an insulated test lead on this channel.
   Use a wire size sufficient to handle the maximum current.

2. Set the output voltage to the maximum rating on this channel.

3. Turn on the channel output. Ensure the channel you used is in Constant Current output mode.

4. Set some different current values on this channel; check if the actual current value displayed is close to the set current value, and to check if the actual voltage value displayed is nearly zero.

5. Check that if the output current can be adjusted from zero to the maximum rating, When it is set to the maximum or minimum, a beep is heard, indicating that the limit has been reached..

6. Turn off the channel output and remove the short circuit from the output terminals.
