Clear OVP Protection
When over-voltage protection occurs, the instrument responds as follows:
•
Instrument output is off;
•
The buzzer sounds;
•
The interface displays “Over Voltage Protect” and flashes
•
Status register, the OV status bit is set to 1.
To clear the over-voltage and return to normal operation, firstly remove the
conditions that caused the protection fault. Press
[Esc]
key (or send the
command PROTection:CLEar) to clear the protection status. The “Over Voltage
Protect” displayed in front panel is cleared and the instrument exits OVP status.
6.2 Set Over-Current Protection
Over-current protection function allows the user to enable the protection and set
a over-current limit (Level) and delay time (Delay). This function prevents the
output current from being higher than the limited output current and protects the
connected DUT so it this is not over-current and possibly damaged due to an
excessive current.
An over-current protection will occur if:
•
Enable OCP;
•
The output current value is greater than the set current protection point
Level and the period is greater than the set protection delay time Delay.
Enable OCP
1. Press
[Shift]+[R-set]
(Protect) to enter Protect menu interface.
2. Rotate the knob to select OCP and press
[Enter]
key to confirm.
3. rotate the knob to select On and press
[Enter]
key to confirm.
4. Rotate the knob to adjust the over-current limit Level and press
[Enter]
key
to confirm.
5. Rotate the knob to adjust the delay time Delay and press
[Enter]
key to
confirm.
6. Press
[Esc]
to exit.
Delay time
You can specify an OCP delay to prevent momentary output settings, DUT and
status changes from tripping the over-current protection. In most cases these
momentary conditions would not be considered an over-current protection fault,
and having an OCP condition disable the output when they occur would be a
