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.
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
the configuration menu.
2. Select
Mode
and press
[Enter]
to enter into the setting interface.
3. Select
CC
or
CV
, and press
[Enter]
.
Enter the setting interface of the loop response speed.
4. Select
High
or
Low
, and press
[Enter]
.
At this point, return to the Config menu settings interface.
5. Press the down arrow key to set the voltage/current rise time. When finished,
press
[Enter]
.
6. Set the other Config menu items in the same way.
7. Set the output voltage and current value.
