Voltage detection

1. The final figures is the voltage value.
2. It will indicate the lower value if not reach 70%of display value of the high value.
3. Please touch the negative pole when test the voltage of DC.
4. Inductance can be used when test the item with lower than 12V voltage
5. It must be connected to ground or the zero when test the item with the induction.
            

Sensor detection
When detect line side by side, please increase the space between the lines
or hand-hold the detected item.

Break detection
Move along the phase line, when there is nothing shows in the display
window, it is the breakpoint.
