(1) Select the required voltage range and verify that the voltage
displayed in the upper voltage display area is correct.
(2) Insert a red LV test wire into the positive electrode of the LV
output, and connect the other end to the positive electrode of the
device to be tested; Insert the black LV test wire into the negative
electrode of the LV output, and connect the other end to the
negative electrode of the device to be tested.
(3) After pressing the LV ON/OFF button, the LED light (green) of
the button is always on, and the digital power supplies power to
the device under test according to the set voltage value.
(4) If it is required to stop the LV output, press the LV ON/OFF
button again. The LED light of the button (green) will be off, and
the digital power will close the LV output.

one end of the HV extension cable into the HV output port (with a
fool-proof anti-reverse insertion design, the positive and negative
signs on the plug are consistent with the positive and negative
signs on the output port before inserting)
Select the corresponding high-voltage test wire (alligator clip-fits
HV wire or banana plug HV jumper cable) as needed. Connect
one end of the test wire to the HV extension cable, connect the
red wire at the other end of the test wire to the positive pole of the
device under test, and the black wire at the other end to the
negative pole of the device under test.
