When discharging, touch the contact point until the LCD lights into a weak light or off.
As long as the LED lights become weak ,you operate it safely,
and weak lighting that the voltage has been below 10V

Note:
When discharging, the discharge tool is not necessary to distinguish between positive and negative,
it is important to note that the edge of the metal tip during the discharge do not touch any conductive objects,
including the human finger and discharge tool itself, two metal nib.
Instructions:
　 when indicated light tending to darkness,
taking off 2 seconds, then repeat discharge again.
Confirm the indicated light become Completely dark,
which shows it is achieve safe operating voltage
(Safe operating voltage range should under 10V)
