Chapter3 Function And Features; Switching Of Local Remote Operation Modes; Constant-Status Operation Mode - ITech IT8300 Series User Manual

This Chapter will give a detailed description of functions and features of the
electronic load. The operation step data in this chapter are only for reference.
For actual data, refer to specific models and specifications.
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.
Load current
Under CC mode, the electronic load provides three ways to set constant
current.

Rotate adjusting knob to set constant current value.

Use numeric keys to input current value and press [Enter] key to confirm
set constant current value.

Use
corresponding positions.
