5.6.1 Current RMS Protection
The user can set the over-current protection point, delay time and protection
type for the Current RMS protection function. The function is mainly used to
protect the DUT connected during test to prevent it from damage due to over-
current. The OCP (rms) function is always enabled.
RMS OCP Type:
⚫
Limit: If the output current reaches the RMS current protection point, the
protection will be activated. The power supply output current is controlled
within the current limiting value. The power supply will output in current limit
mode.
⚫
Shutup: When the output current reaches the over-current protection point
and the period is greater than the set protection delay time, the over-current
protection (rms) will turn off the output.
How to Set
1.
Press [Shift]+[Config] (Protect) keys and enter to Protection menu.
2.
Press the up/down key or rotate the knob to select Current RMS protection
and press [Enter].
3.
Set the protection RMS Level, the delay time and protection type in
sequence, and press [Enter] to confirm.
Clear RMS OCP Protection
When RMS OCP protection occurs, the instrument responds as follows:
⚫
Instrument output is off;
⚫
The buzzer sounds;
⚫
The interface displays “OCPrms” and flashes
To clear the RMS OCP and return to normal operation, firstly remove the

[Shift] +[Esc]
key (or send the
command PROTection:CLEar) to clear the protection status. The message
displayed in front panel is cleared and the instrument exits protection status.
5.6.2 Set the Current Peak protection
The user can set the current peak protection point and delay time for the Current

connected during test to prevent it from damage due to over load. The OCP
peak function is always enabled.
How to Set
1.
Press [Shift]+[Config] (Protect) keys and enter to Protection menu.
2.
Press the up/down key or rotate the knob to select Current peak protection
