or current range) to switch current range and choose V rAn (i.e., V Range or voltage range) to
switch voltage range.
During the switching of voltage range, the voltage limit will be reset to the maximum value
allowed within the current range.
During the switching of current range, the current limit will be reset to the maximum value
allowed within the current range.
During the switching from the high range to the low range, any associated settings that
exceed the maximum value allowed within the low range will be capped at that maximum value.
2.3. Channel Switching
Press the [ON] button to activate or deactivate the channel.
When the channel is active, the "ON" character in the upper right corner of the interface will
be displayed.
Once the channel is enabled, if it remains in an open circuit state (i.e., an input voltage of 0 or
less than the startup voltage is detected, indicating that the load isn't functioning and remains in a
high resistance state), the "ON" indicator will flash, indicating that the channel is in informal
operation mode.
When the channel is disabled, the "ON" character in the upper right corner of the interface
will not be displayed.
2.4. Remote/Local Switching Operation
Upon receiving a SCPI command, the load will detect the end character '\n' of the SCPI
command and lock the buttons, with the LOCK icon displaying on the interface. At this point, all
buttons except for the [ENT] are disabled. Press the [ENT] button to switch from remote to local,
release the button lock status, and remove the LOCK icon.
2.5. System Setting Operation
When the channel is inactive, press the [MENU] button to enter the system menu interface on
which [▲▼◄►] arrow buttons, [ENT] and [ESC] can be used to adjust system settings, while
other buttons are disabled.
In the system menu interface, users can perform operations such as saving parameters,
recalling parameters, trigger source selection, starting voltage, turn-off voltage, buzzer, backlight
brightness, etc.
2.5.1. Saving Parameters
Within the system menu, the Save Parameter Interface is illustrated in Fig. 2-5-1-1. SavE
PArA Set represents Save Parameter Setting.
