Constant Current Output
In constant current output mode, the output current equals the current setting value
and the output voltage is determined by the load. This section introduces the
operation method in constant current output mode.
Operation Method:
1. Turn on the power switch to start the instrument.
2. Select the channel
Select the proper output channel according to the desired output current. Press
the corresponding channel selection key; at this point, this channel, its channel
number and output state are high-lighted in the center of the screen.
3. Set the voltage
Press Voltage to set proper voltage according to “Set the voltage” in
“Constant Voltage Output”.
4. Set the current
Press Current to set proper current according to “Set the current” in
“Constant Voltage Output”.
5. Set the overvoltage protection
Press OVP to set the proper overvoltage protection value. For the setting
method, refer to “Set the voltage” in “Constant Voltage Output”. Press OVP
again to enable the overvoltage protection function and the output will be
turned off automatically when the actual output voltage is greater than the
overvoltage protection value.
6. Connect the output terminals
As shown in the figure below, connect the load to the output terminals of the
corresponding channel.
CAUTION
To avoid damaging the instrument or the device connected to it, pay
attention to the polarity when connecting.
7. Turn on the output
