Triggering a preset level
Transfer all pending preset levels to the immediate levels. For the presently active mode, the new
level will appear at the input at once if the input is turned on. For the modes which are not
presently active, the preset levels will not take effect at the input until the corresponding mode
becomes active.
Triggering a transient pulse
Gernerate a transient pulse in accordance with the preset transient parameters, when pulsed
transient operation is active.
Triggering a transient toggle
Switch the input between the transient low level and transient high level in accordance with the
preset transient parameters, when the toggled transient operation is active.
Triggering a list test
Enable the present list test when the list operation is active.
Three triggering methods are available for remote control: GPIB <GET> signal, the *TRG and
TRIGger commands. The External trigger input terminal and
key +
key on the front panel
of the load can be used to trigger as well.
The load has three triggering modes: BUS, EXTernal, and HOLD.
The BUS mode:
the trigger source is GPIB <GET> signal, or *TRG command.
The EXTernal mode:
Choose the External trigger input terminal or
key +
key
on the front panel as the trigger source. The input signal at the External trigger input terminal
is TTL, the falling edge (signal) is triggered..
The HOLD mode:
Use TRIGger:IMMediate command as the trigger source. At this time,
all other triggering methods including *TRG become invalid.
Note: The TRIGger:IMMediate command can be used in all three triggering modes. The
triggering modes can be selected via the remote command only (TRIGger:SOURce BUS;
TRIGger:SOURce EXTernal; TRIGger:SOURce HOLD).

Input Control
2.9.1
Turning On/Off the Load
The input can be turned on/off by pressing
key, or via the remote command (INPUT
ON/OFF). If the load’s input stays in OFF status, press
key to turn on the input; if the load’s
input stays in ON status, press
key to turn off the input. Turning the input on/off (zero current)
does not affect the programmed settings
.
In local control, if the input is turned on, the load status can not be switched directly among the
basic modes, transient operation, list operation, battery discharge operation, etc. The load can be
switched from one operation status to another operation status only when the input is turned off.
