the DUT. Press Shift and Display key to clear overvoltage protection status.
Overcurrent protection (OCP)
The load supports two kinds of overcurrent protections: Hardware
overcurrent protection and software overcurrent protection.
 Hardware overcurrent protection: The maximum load current of the
electronic load is limited to the max current of the existing current
range by hardware. When the hardware triggers overcurrent protection,
the load will automatically disable the input and the LCD screen will
pop-up an overcurrent message. The prompt box of overcurrent
protection will disappear if the input drops below the set current range
(I_Range).
 Software overcurrent protection: For a more precise protection limit,
you can set the load software overcurrent protection value using the
following steps:
Press Shift and CP key to enter system utility interface. Then press
“Limit” and “I_Protect” to set relevant parameters, such as current
value and delay time. If the load sink current is greater than the
protection current value, the load input will automatically be disabled
and an overcurrent message will pop-up.
To exit OCP protection, press any key on the front panel of the load. .
Overpower protection (OPP)
The load supports two kinds of overpower protections: Hardware
overpower protection and software overpower protection.
 Hardware overpower protection: The maximum load power of the
electronic load is limited within about two hundred watt. When the
hardware triggers overpower protection, the load input will be disabled
automatically and the LCD screen will pop-up an overpower message.
The prompt box of overpower protection will disappear if the hardware
overpower protection situation is relieved.
 Software overpower protection: The user can set load software
overpower protection value following steps: Press Shift and CP key to
enter system utility interface. Then press “Limit” and “I_Protect” to set
relevant parameters, such as power value and delay time. If the sink
