Power switch fault: The power switch is damaged or improperly connected. As a result, the power cannot be started.
Blown fuse: The fuse in the power supply circuit is blown due to overcurrent, overvoltage and other reasons, resulting in the device cannot supply power.
Fault: The constant current mode is abnormal
Reason analysis:
The connection line is reversed: the connection line between the instrument and the device under test is reversed, resulting in the wrong current direction.
Input voltage/current over rated power: The input voltage and current value of the load exceed the rated power of the instrument, causing the device protection mechanism to start.
Improper load current setting range: If the load current setting range is inappropriate, the device may fail to work properly or the protection mechanism may be triggered incorrectly.
By understanding the common faults of the equipment, you can better maintain and use it to ensure its long-term stable operation. If you can not solve, welcome to contact Hao Chen!
