：

: Used to turn on/off the tester

6. Operation steps

Determine the faults properties

6.1. Cable Break

One or several cable cores disconnect

6.2. Cable Mix

The insulation falls between the cable cores, and cause

the signal attenuation bigger

6.3. Geo-Gas

Insulation drops between core wires to ground

6.4. Cross-Talk and noise

Cable wires soaking, and the capacitance is bigger, this

will affect the communication

6.5. Poor Insulation

Insulation drops between cable wires or between cable

wires to ground.
