3.1 Switching of local/remote operation modes
The electronic load is provided with local and remote operation modes. These
two modes can be switched through communication commands. At initialization,
the electronic load is defaulted under local operation mode.
⚫
Local operation mode: for operating related functions through keys on the
electronic load machine.
⚫
Remote operation mode: for operating related functions of the electronic
load on PC through a connection between the electronic load and PC.
Under remote operation mode, except
[Local]
key, other keys on the board
are disabled. The
[Local]
key can be used for switching to local operation
mode.
3.2 Constant-status operation mode
The electronic mode can work under the 4 constant-state operation modes:
⚫
Constant current operation mode (CC)
⚫
Constant voltage operation mode (CV)
⚫
Constant resistance operation mode (CR)
⚫
Constant power operation mode (CW)
3.2.1
Constant current operation mode (CC)
Under CC mode, the electronic load will consume constant current in regardless
of whether the input voltage changes or not, as shown in Fig. 3-1.
