Constant Voltage Output
DP800 series power supply provides three output modes: constant voltage output
(CV), constant current output (CC) and critical mode (UR). In CV mode, the output
voltage equals the voltage setting value and the output current is determined by the
load; in CC mode, the output current equals the current setting value and the output
voltage is determined by the load; UR is the critical mode between CV and CC. This
section introduces the operation method in constant voltage output mode.
Operation Method:
1. Connect the channel output terminals
As shown in the figure below, connect the load with the channel output
terminals of the corresponding channel on the front panel.
Pay attention to the polarity when connecting them to avoid damaging
the instrument and the devices connected to the instrument.
2. Turn on the power switch to start the instrument.
3. Select the channel
Select the proper output channel according to the desired output voltage. 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
Method 1
Press Voltage and use the left/right arrow key to move the cursor; then, rotate
the knob to quickly set the voltage and the default unit is V.
After selecting the
digit to be set, you can also use the up/down arrow key to modify the value of
the corresponding digit. The default unit is V.
Method 2
Press Voltage, use the numeric keyboard to directly input the desired voltage
value and press V or mV or press the unit selection key ( or ) to
