2.1 Output summary
 The SPD1000X provides a floating output. The output rating of the
SPD1168X is 0-16 V / 0-8 A，while the output rating of SPD1305X is 0-30
V / 0-5 A;
 Two modes of output: constant voltage (CV) and constant current (CC);
 Two types of operation: two wire mode and remote sense mode.
Constant voltage output/constant current output:
In the constant current mode, the output current is a set value which can
be controlled by the front panel. The user interface displays the output mode
is ‘CC’ and the current is still in a set value. At this time, the voltage is lower
than the set value. When the output current is less than the set value, the
constant current mode will switch to constant voltage mode automatically.
In the constant voltage mode, the output current is less than the set value,
which can be controlled by the front panel. The user interface displays the
output mode is ‘CV’ and the voltage remains at the set value. When output
current reaches the set value, the system switches to the constant current
mode.
2-wire mode/remote sense mode:
When the SPD1000X is set to the 2-wire mode, the display prompt
displays the working mode as “2-wire.” When the output is on, the instrument
will detect and display the output terminal’s actual output mode automatically.
In the remote sense mode, the prompt displays the working mode as
“remote sense.” When the output is on and the remote sense terminal
connect to the load, the instrument will detect and display the actual output.
