constant. Instead, the unit will now regulate the output voltage at its voltage limit
setting.
As shown by the horizontal portion of the shaded quadrants, when the unit is
sinking power, the output current may continue to increase in the negative direc-
tion as more current is forced into the unit. This can happen when the instru-
ment is connected to an external device such as a battery, and its output
voltage is higher than the voltage limit setting of the instrument. Once the cur-
rent exceeds the built-in negative over-current limit, the output will shut down. In
such a case, it is important to set the voltage limit properly in order prevent this
protection shutdown.
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. Press the down arrow key to set the voltage/current rise time. When finished,
6. Set the other Config menu items in the same way.
7. Set the output voltage and current value.

4.4.2 Set the Internal Resistance

The IT6000C series power supply provides internal resistance setting (CV prior-
ity mode only). The procedures are shown as below.
the configuration menu.
Enter the setting interface of the loop response speed.
At this point, return to the Config menu settings interface.

CV priority
a. Press the [V-set] key on the front panel to set the output voltage val-
ue Vs.
b. Press the [I-set] key on the front panel to set the current upper limit I
+. Press [I-set] again to set the current lower limit I-, i.e. the negative
current limit value.
•
CC priority
a. Press the [I-set] key on the front panel to set the output current value
Is.
b. Press the [V-set] key on the front panel to set the voltage upper limit
Vh, and press [V-set] again to set the voltage lower limit Vl.
