Output Recall
This parameter determines the output state when the power supply is powered on. If you select On for
the output recall function, the power supply will restore the output state to that which was in use before
the power was last turned off. If the output was turned on when the power supply is turned off or loses
power, then the output will return to the On state when the power supply is turned back on or power is
restored. If you select Off for output recall function, the output channel will always be set to off after
the power supply is powered on.
To enable/disable the function:
1. Push Menu.
2. Use the arrow keys to select User settings.
3. Push Enter. The screen will display Output Recall.
4. Push Enter.
5. Use the arrow keys to select On or Off.
6. Push Enter.
7. Push Esc to exit the menu.
Save Last
This item determines whether the power supply saves its most recent settings, such as voltage and
current, and restores these settings at power on. If you set this item to On, the power supply will
restore the instrument to the state that it was in before the power was last turned off. If you select Off,
then the factory default settings are used (sets voltage to 1V and current to 0A for each channel)
To enable/disable this function:
