Entry keys:
^
and
v
. The UP and DOWN keys allow you to scroll through the choices in a
parameter list that is applied to a specific command. Parameter lists are circular;
you can return to the starting position by pressing either of the keys continuously.
ON/OFF
. Toggles the output of the electronic Load between on and off states if
channel SYNC. RUN is set to ON.
ENTER
. Executes the entered value or the parameter of the presently accessed
command. The parameters you have entered with other keys are displayed but
not entered into the Load until you press this key. Before pressing ENTER you
can change or abort anything previously entered into the display.
SHIFT
. Enables a shifted key to function (LOCK, SYS). When in remote control
state, this key acts as a local key.

4.2.1 Selecting the Channel
The CHAN key is used to select one of the channels for local control. See channel
number in 2.3.1. To edit channel settings, you must select a channel first. If the
channel does not exist, it cannot be selected. If no module is installed in the
mainframe, the display will show
DUMMY CHANNEL
. When you press CHAN, the
channel number you want to select will automatically increase to the next existing
channel. The mainframe will scan the module type at power-on, and memorize it for
channel editing.
4.2.2 Setting the Operation Mode
The MODE key and the
^
and
v
keys are used to select modes of channels for local
control. Press MODE to display the selected channel’s active mode. The active
mode can be changed by use of the
^
or
v
key followed by the ENTER key. The
sequence of mode selection after pressing the
v
key is as follows:
CCL -> CCH -> CCDL -> CCDH -> CRL -> CRH -> CV go back to CCL.
Press the ENTER key to select the mode and confirm the setting.
NOTE:
The eight operation modes of load module settings stored in the mainframe
are independent. Changing one mode setting will not affect other modes. Storing the
settings to EEPROM (1-100) will store only one mode setting.
The load levels and slew rates are common to CC and CR modes. CV mode sets
voltage level and response speed. There are two level settings for a single channel/
module of CC, CR, and CV modes. They can be switched by the module’s A/B key.
