1. Turn on the power supply.
Press Power-on button and finish the power-on checkout. Usually the power supply will go into the
power-on / reset state automatically and the “OFF” annunciator in the lower right corner of the LCD turns
on. Both the voltage value and current value are 0.
2. Connect a short across (+) and (-) output terminals of the supply with an insulated test lead. The
sectional area of the shorting stub should be larger than 1.5mm

.
3. Enable the outputs.
Set the supply voltage to 5V according to the voltage setting measure. Press the OUT on/off button, the
display is in monitor mode. At the same time a 5-digit voltage meter and a 5-digit current meter are
displayed, showing the actual value of output voltage and output current of the power supply respectively.
The CV or CC modes depend on the resistance of the test lead.
4. Adjust the voltage limit value to 1.0 V.
Adjust the voltage limit to 1.0 V to assure CC operation. Please see related chapters about voltage and
current setting from front panel in this manual for specific operations.
5. Check that the front-panel ampmeter properly responds to the key and knob operations from the front
panel.
