Low pressure conduction testing: to test cable applied current, voltage measuring cable ends and current values, the tester of the measurement results using Ohm's law of conversion, the resistance value. The resistor and the user set values were compared with the resistance value, to determine whether to meet the requirements of the user's index, and will result in the "pass" or "fail" clear information displayed on the user computer paraded.

Insulation test: through low conduction test, insulation test. To meet the currentuser set value, the value of measuring insulation resistance. And the determinationto "pass" or "fail" clear information displayed on the user computer paraded.Pressure test: high voltage applied time on the need to test cable, current measurement on the cable, if the actual current exceeds the current value set by the user, is that the cable is not qualified.
