1:LED lamp (by NO/OFF)

LED lights can be seen in the dark night.

2: detection of various types of household appliances (by direct)

Can detect the hair dryer, washing machine, electric cooker and all power plug test (level two, light circuit intact; bright lights show the trouble. )

3: the detection line (by direct key )

Check the electrical wiring decoration strands using the pen off function can quickly identify a line or break in the line ends charged situation

4: detection of alternating current (by direct bond)

This leads to liquid crystal display voltage value of last digits are the measured voltage

5: Test DC (direct press key)

estimation of battery power: by hand battery cathode, anode by light pen without electricity, dark bright electric light, not enough power

6: indirect test (not by high-voltage electric power construction )

indirectly tested up to one thousand volts. The pen body into the measured object, the light is not bright, there exists high voltage

7: zero line search resolution (by induction key) breakpoint

The two side by side line separate test, display charged is the symbol of the line. If there is a breakpoint, live circuit mobile pen, charged disappear is breakpoint symbol

8: night vision

In the night detection can clearly observe the digital display

9: self check function

before use self lights not bright work, please replace the battery
