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. Connect the channel output terminals

Connect the load with the channel output terminals of the corresponding

channel at the front panel by referring to "Connect the channel output

terminals" in "Constant Voltage Output".

2. Turn on the power switch to start the instrument.

3. 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, output state and output mode are high-lighted on the screen.

4. Set the voltage

Press Voltage to set the desired voltage according to "Set the voltage" in

"Constant Voltage Output".

5. Set the current

Press Current to set the desired current according to "Set the current" in

"Constant Voltage Output".

6. Set the overvoltage protection

Press OVP to set a proper overvoltage protection value (for the setting method,

refer to "

Set the voltage" in "Constant Voltage Output"). Then, enable the

overvoltage protection function (you can enable or disable the OVP function by

pressing OVP) and the output will be turned off automatically when the actual

output voltage is greater than the overvoltage protection value.

7. Turn on the output

Turn on the output of the corresponding channel and the actual output voltage,

output current, output power as well as the output mode (CC) are high-lighted

in the user interface.

Warning

To avoid electric shock, please turn on the output switch after the output

terminals are correctly connected.
