RMX Programmable Power Supplies User Manual
Preset Memory Function
RMX programmable power supplies have a preset memory function that allow users to store
three sets of the following settings: voltage setpoint, current setpoint, and OVP/OCP/UVL trip
points. These settings can be recalled from the preset memory slots whenever they are needed.
To save the current settings into a preset memory slot, hold down the shift key and the key for
the slot you'd like to save the settings to (A, B, or C) until the key's LED illuminates.
To recall a set of saved settings, hold the shift key and press the key for the slot you'd like to
recall (A, B, or C). The settings will go into effect the moment you press the memory slot key.
The recalling will be effective at the moment when you select the preset memory. To save the
present settings, you need to keep holding down the keys (SHIFT+A, B, or C).

Press SHIFT+ the memory key (A, B, or C) to which you want to save the settings. Hold
the keys down until their LEDs turn on.
The PRESET A, PRESET B, or PRESET C LED in the display area—whichever one
corresponds to the memory entry that you selected—lights to indicate that the preset
memory entry has been saved.
You can save preset memory entries when the output is on and the measured value display is
being shown (the SET key LED is off). After you save a preset memory entry, press SET to view
the preset memory values.
