3.5.3 Constant Voltage Mode
Figure 3-14 Constant Voltage Mode
In CV mode the Load will sink current to control the voltage source in programmed value.
This mode is operated under the F/W calculation. That is, take the voltage setting, divide the
measured output current of UUT’s CC mode and get the suitable resistance as the
equivalent resistance of the Cells. Then, take the voltage setting, divide the suitable
resistance and get the I setting value. There is a moving average calculation process for the
measuring data. High frequency parts will be removed, and the minimum transient time of the
loading current in this mode is 400
μs.
Voltage can be programmed in any of low range, middle, or high range by the key.
The low range is used for input voltage in low voltage range. The middle range is used for
input voltage in middle voltage range while the high range is for the input voltage over middle
voltage range.
In some modules (single channel module), there are two voltage levels (A or B) for CV
function. You can select state A or state B using key. Both A and B states use the
same range.
Current Range (High)
The current range in CV mode is high range.
