Chapter 2 Basic Functions
Recalling Preset Memory Entries
You can recall preset memory entries from the measured value display (when the SET key LED
is off) and from the setting display (when the SET key LED is lit). If the output is on, the values
in the preset memory entry are applied to the output the moment that the preset memory entry is
recalled.
There are two methods to recall a preset memory entry. One method is to display the saved
contents for confirmation and then recall (CF04: on). The other is to recall immediately without
displaying the contents (CF04: oFF).
When you recall a preset memory entry, the following items are set to their factory default settings.
• Constant current control using an Vext or Rext (CF05: oFF)
• Constant voltage control using an Vext or Rext (CF06: oFF)
• Output on/off control using an external contact (CF09: oFF)
• Current setting limit (CF14: on)
• Voltage setting limit (CF15: on)
Complete the following steps to display the saved contents for confirmation and recall.
1. Press SHIFT+ the memory key (A, B, or C) from which you want to recall the preset
memory entry.
The SET LED and the contents (voltage and current) of the loaded preset memory that are
shown in the display area blink. If you press another memory key, the contents of the
corresponding memory appear blinking.
Note This is convenient when you want to view the contents that have been saved
to memory.
2. Check the displayed settings, and then press SET.
The SET LED and the LED that corresponds to the loaded preset memory entry both light,
and the set voltage and current are displayed on the panel.
Note Press OCP•OVP, CONFIG, or PWR DSPL to cancel the recall operation.
Complete the following steps to recall without displaying the saved contents.
1. Use the CONFIG settings to set the RMX programmable power supply to hide the saved
contents of preset memory entries (CF04: oFF).
Note This is convenient when you know the contents that have been saved to
memory.
2. While holding down the SHIFT key, press the appropriate memory key (A, B, or C).
The LED that corresponds to the preset memory entry that you have loaded (PRESET A,
B, or C) lights.
