To clear an overprotection error using the front panel:
When the overprotection error dialog box is displayed, you can press the ENTER key to initiate the
trigger model.
To clear an overprotection error using a SCPI command:
When an overprotection error occurs, send the following command to clear the register and initiate
the trigger model:
:OUTPut:PROTection:CLEar
Maximum voltage limits
The maximum voltage limits prevent the instrument from sourcing a voltage over a maximum voltage
limit. This helps prevent damage to the device under test (DUT).
You cannot specify a voltage setting over the maximum voltage limit. If you set a maximum voltage
limit that is smaller than the voltage source value, the source value is automatically changed to the
maximum voltage limit.
Setting maximum voltage limits
To set the maximum voltage limit using the front panel:
1. Press the MENU key.
2. Under Source, select Protect.
3. Select VMax and set the limit.
4. Select HOME to return to the operating display.
To set the maximum voltage limit using SCPI commands:
Send the :SOURce:VOLTage:LIMit command with the value of the limit. For example, to set the
voltage limit for the current source to 25 V, send the command:
:VOLTage:LIMit 25
See the command description for [:SOURce[n]]:<function>:PROTection[:LEVel] (on page 7-76) for the
full list of options.
