The heavy solid line illustrates the locus of possible operating points as a func-
tion of output. As shown by the vertical portion of the line, the output current re-
mains regulated at its programmed setting as long as the output voltage
remains within its limit setting. A CC (constant current) status flag indicates that
the output current is being regulated and the output voltage is within its limit
settings.
Note that when the output voltage reaches the upper limit, the unit no longer op-
erates in constant current mode and the output current is no longer held con-
stant. Instead, the unit will now regulate the output voltage at its voltage limit
setting.
How to Set
The procedures to set the output priority mode are as follows.
1. Press the composite keys [Shift]+[V-set] (Config) on the front panel to enter
2. Select Mode and press [Enter] to enter into the setting interface.
3. Select CC or CV, and press [Enter].
4. Select High or Low, and press [Enter].
5. Rotate the knob to set the voltage/current rise time. When finished, press
6. Set the other Config menu items in the same way.
7. Set the output voltage and current value.
the configuration menu.
Enter the setting interface of the loop response speed.
At this point, return to the Config menu settings interface.
