1,wiring
Correctly connect the input and output to ensure that the range of input voltage requirements, the reverse is prohibited.
2, set the voltage and current values
After the power-on default display format is the voltage set value, the voltage value displayed is "00.00", the unit is "V", for example, "12.00" means "12.00V". Press the "SET" button to switch to the current set value, the current value of the display format is "0.00A", the unit is "A", such as "1.20A" indicates "01.20A".
Setting method: Press the button to increase the value, press the button to decrease the set value, press accurately set, press can be quickly set. Press the "SET" button to switch to set the current or voltage value.
3, open output
After setting voltage and current values, you can directly press "OK" key to output, output after press "OK button" to switch voltage and current display.
4, adjust the output voltage and current values under the state
Output state when the voltage value is displayed by pressing the button on the output voltage can be increased by pressing the button under the output voltage can be reduced by pressing the button you can increase the current set value when displaying the current value, press the next button can reduce the current setting, press accurately set, press can be quickly set.
5, turn off the output
Output state, press the "SET" button to turn off the output.
6, the automatic power-output function
Automatic power-output function is enabled:
Press "SET" button to enter the parameter setting page, click on the button to adjust to "-F2-" option, then click on the "OK" button, digital display "Yo-0", click on the button, the display switches to "Yo -1 ", and finally click" OK "button to save the settings.
Auto power-output function close method:
Press "SET" button to enter the parameter setting page, click on the button to adjust to "-F2-" option, then click on the "OK" button, digital display "Yo-1", click on the next button, the display switches to "Yo -0 "and finally click" OK "button to save the settings.
7, function display output capacity
Under the current status display, press the "OK" button for 3 seconds to display x.xxC; capacitance value at that time is displayed, press "OK" button to restore the current display.
In the display voltage state, long press the "OK" button to display x.xxH more
than 3 seconds; the value of the time value is displayed, press "OK" button to restore the voltage display.
8, parameters save, recall
Save parameters:
Press "SET" button to enter the parameter setting page, click on the button or down button to adjust the "-F0-" option, then click on the "OK" button, digital display "Sn-0", click on the button or down button to change the address, and finally click "OK" button to save a good set parameters are saved to the corresponding address bits.
Parameters recall:
Press "SET" button to enter the parameter setting page, click on the button or down button to adjust the "-F1-" option, then click on the "OK" button, digital display "Lo-0", click on the button or down button to change the address, and finally click "OK" button to save parameters corresponding address bit out of tune.
