Remote Programming
The electronic load may be remotely programmed from the computer via the IT-E131 isolated communication cable
.
Operating Modes
The four modes of operation are:
1: Constant current (CC).
2: Constant voltage (CV).
3: Constant resistance (CR).
4: Constant power (CW)

）Mode
In this mode, the electronic load will sink a current in accordance with the programmed value regardless of the input
voltage. CC mode can be set with front panel keys. The CC mode parameters are discussed in the following paragraphs.

CONSTANTCURRENT MODE
Constant Resistance (CR) Mode
In this mode, the module will sink a current linearly proportional to the input voltage in accordance with the programmed
resistance. The CR mode can be set at the front panel. The CR mode parameters are described in the following paragraph.

CONSTANT RESISTANCE MODE
Constant Voltage (CV) Mode
In this mode, the electronic load will attempt to sink enough current to control the source voltage to the programmed value.
The module acts as a shunt voltage regulator when operating in the CV mode. The CV mode can be set at the front panel.
The CV mode parameters are described in the following paragraphs.
