User Settings
(Save and
Recall)
If you have a frequent or constant need for a specific voltage and current output, you
can save these setpoints in the power supply’s memory as a user setting. Once a
setting is stored, it remains in the power supply’s memory after the unit is powered
off.
Ten user setting memory locations are available, and each saves the following
parameters:
• Voltage setpoint
• Current setpoint
• Over-voltage protection setpoint (OVP)
• Under-voltage protection setpoint and shutdown configuration (UVP)
• Over-current protection setpoint and shutdown configuration (OCP)
• Under-current protection setpoint and shutdown configuration (UCP)
• Foldback protection mode and delay settings
• AC Off auto recovery configuration (ACO)
• OTP auto-recovery configuration
• Aux line configuration
• Voltage and current soft limits
• Triggered setpoints and trigger source
To store (save) settings:
*SAV <user-setting>
or the SCPI equivalent for multichannel addressed units
SYST<channel>:SAVE <user-setting>
where <user-setting> is an integer from 1 to 10.
Example:
*SAV 1 will save all the present settings to user setting location 1.
To recall settings:
*RCL <user-setting>
To save default settings:
*SDS <user-setting>
Note All parameters are saved and used when the user setting is recalled. Therefore, you
should set parameters that you do not care about to the factory defaults.
