Constant Voltage Mode

In CV mode the Load will sink current to control the voltage source in programmed value.
There are two response speeds of CV modes: fast and slow. The fast/slow respond speed is
the slew rate of current change.
Voltage can be programmed in either of low range or high range by the
low range is used for input voltage in low voltage range while the high range is for the input
voltage over low voltage range.
There are two voltage levels (A or B) for CV function. You can select CVHA or CVHB
using key.

Constant Power Mode

In CP mode, the Load will sink a current according to the programmed power. This mode is
operated under the F/W calculation. That is, take the measured V data, divide the Power
setting and get the I setting value. High frequency parts will be removed as there is a lower
