NOTE
When the set current is within small range, current display resolution will be improved.
3.2.2
Constant voltage operation mode (CV)
Under CV mode of IT8900, you can set limit current (Limit). When the set limit
current is higher than the input current, the electronic load will work under
constant voltage; when the set limit current is lower than the input current, the
electronic current will be loaded with set limit current and the voltage is input
voltage. As shown in Fig. 3-2.
Fig. 3-2 Voltage-Current Relation Schema under CV Mode
Under CV mode, the electronic load provides three ways to modify constant
voltage.
⚫
Rotate adjusting knob to set constant voltage value.
⚫
Use numeric keys to input voltage value and press
[Enter]
key to confirm
set constant voltage value.
⚫
Use
moving cursor and press
to adjust values at
corresponding positions.
