The following steps verify basic voltage functions without load:

When the instrument is under no load, select a channel and ensure the output current setting for this channel is not at zero.
Turn on the channel output, then ensure the channel is in Constant Voltage output mode.
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.
Check that if the output voltage can be adjusted from zero to the maximum rating.

3.4.2 Current Output Inspection

The following steps check basic current functions with a short across the power supply's output:

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.
Set the output voltage to the maximum rating on this channel.
Turn on the channel output. Ensure the channel you used is in Constant Current output mode.
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.
Check that if the output current can be adjusted from zero to the maximum rating.
Turn off the channel output and remove the short circuit from the output terminals.

4.6 Output mode

Output mode can simplify the parameter inputting of CH1 and CH2. Output mode setting is only for CH1 and CH2, without affecting CH3. There are four output modes:

Independent Output: The parameter of each channel can be set independently.
Parallel mode: When CH1 and CH2 are connected in parallel, you can select this mode to simplify the parameter inputting. You just need to set the parameters of the combined channel. The voltage rating is same as the single channel; the current rating is the sum of CH1 and CH2 current rating. Press the yellow/blue On/Off key to turn on/off the combined channel.
The connection method of the parallel connection of CH1 and CH2 is as shown in the figure below.
Series mode: When CH1 and CH2 are connected in series, you can select this mode to simplify the parameter inputting. You just need to set the parameters of the combined channel. The voltage rating is the sum of CH1 and CH2 voltage rating; the current rating is same as the single channel. Press the orange On/Off key to turn on/off the combined channel.
The connection method of the series connection of CH1 and CH2 is as shown in the figure below.
Channel track: In independent output mode, set the output parameters of CH1 and CH2, and then enter the channel track mode, if the parameters of any one channel are changed, the other channel will change proportionally. For example, in independent output mode, set the CH1 voltage to 2V, current to 1A; set the CH2 voltage to 4V, current to 2A. After entering channel track mode, if CH1 voltage is set to 6V, CH2 voltage will be adjusted to 12V proportionally. If CH1 current is set to 2A, CH2 current will be adjusted to 4A proportionally.
Note: If the setting value is out of the rated range, it will be set to the maximum.

To set the output mode:

Press the Utility key. Then press Mode to enter output mode menu.

5. Troubleshooting

The instrument is powered on but no Display:
- Check if the power is connected properly.
- Check if the fuse which is below the AC Power socket is used appropriately and in good condition (the cover can be pried open with a straight screwdriver).
- Restart the instrument after the steps above.
The output is abnormal:
- Check if the output voltage is set to 0V. If so, set it to other value.
- Check if the output current is set to 0A. If so, set it to other value.
- When in programmable output status, check if there is any voltage/current value is set to 0. If so, set it to other value.
Cannot identify the USB device correctly:
- Check if the system settings prioritize USB devices. If you want to use a USB flash drive, set USB devices as the priority.
- Check if the USB device is in good condition.
- Check if the used USB device is a flash device, note a hard disk cannot be supported.
USB cannot communication:
- Check if USB communication is prioritized in the system settings. If you want to use USB communication, set USB communication as the priority.
- Check if the used USB device is a flash device, note a hard disk cannot be supported.

If you encounter any other issues, please try restarting. If the product still does not function properly, please contact Fujian LILLIPUT Optoelectronics Technology Co., Ltd. for assistance.
