Using the Protection Function
Protection function
Each output has independent protection functions. A front panel status indicator will turn on when a protection
function is set. Protection functions are latching, which means that they must be cleared once they are set.
Of the following protection functions, only OV and OC are user-programmable.
– OV: Over-voltage protection is a hardware OVP whose trip level is a programmable value. The OVP is always
enabled.
– OC: Over-current protection is a programmable function that can be enabled or disabled. When enabled, the
output will be disabled when the output current reaches the current limit setting.
– OT: Over-temperature protection monitors the temperature of each output and shuts down the output if any
temperature exceeds the maximum factory-defined limits.
Configuring protection
Protection functions are configured on the Source Settings window.
Press Source Settings to access the Source Settings window.
OV Protection
Over-voltage protection disables the output if the output voltage reaches the OVP level.
To set the over-voltage protection, enter an over-voltage value in the OV Protection field.
For E36311A or when SCPI ID is set to E3631A, you can program a negative over-voltage protection level
which will disable the output when negative voltages are detected.
