Troubleshooting
The following lists the power supply in the use of the process of possible failures and
troubleshooting. When you encounter these faults, please follow the corresponding steps to
deal with them. If you can't handle them, please contact siglent in time.
A. If the power on key is pressed, the power supply is still black, and there is no display:
➢ Check whether the power connector is connected properly.
➢ After checking, please restart the power supply.
➢ If the power supply can not be started normally, please contact SIGLENT.
B. No voltage output by output
➢ Check whether the voltage and current settings are correct
➢ Check whether the supply is in host mode, whether EXT on/off is in the off state,
Volt_ctrl and Curr_ctrl are in Local state, whether the output resistance is set properly,
whether the output delay time is too large, and the slope mode setting is too small,
which causes the output voltage to rise slowly.
➢ Use the default setting to reset the voltage and current output after restoring the
factory settings.
➢ If the power supply still cannot be used normally, please contact SIGLENT.
C. U disk cannot be recognized:
➢ Check whether the U disk device can work normally.
➢ Check whether the power USB HOST interface is working properly.
➢ Make sure that the flash-type U disk is used, and the power supply does not support
hard disk-type U disk devices.
➢ Re-plug the U disk, or restart the power and insert the U disk again.
➢ If you still cannot use the U disk normally, please contact SIGLENT.
