5. Continuous use time exceeds 200 hours

Instructions:

Turn on the power and insert the network cable plug into the main tester
and the sub-tester respectively. The indicator lights of the host flash from
1 to 8 in order, indicating that the wiring is normal.
If the wiring is not normal, it will be displayed as follows:
1. When a network cable is broken, for example, the No. 3 line is broken,
the No. 3 lights of the main unit and the auxiliary unit are not on
2. When several lines are disconnected, the lights corresponding to the
-se lines are off. When there are less than two network cables connected
normally, all lights are off.
3. When the connection of the two ends of the network cable is
disordered: for example, the 2/4 line sequence is disordered, the
display is as follows:
     Host unchanged: 1-2-3-4-5-6-7-8
     The secondary terminal is: 1-4-3-2-5-6-7-8
4. When there are two short-circuits in the network cable, the
corresponding light on the host end is off, and the corresponding light
on the auxiliary end is slightly on. If there are more than 3 (including 3)
short circuits, the lights corresponding to all short-circuited lines will
not turn on
5. The G indicator will only light up when testing the shielded network
cable. If the G light is off, the network cable has no shielding effect.
6. The tester is powered by 9V battery. If the indicator light is dimmed
or cannot be lit, please replace the battery
