Insulation resistance of wire insulation resistance tester: insulation resistance refers to the resistance value of applying voltage to the insulation part of the adapter, and then causing leakage current to occur in or on the outside of the insulation part. It is primarily affected by insulation materials, temperature, humidity, contamination and other factors.
The value of insulation resistance supplied on the connector sample is generally the target value under the premise of standard atmosphere. In some cases, the value of insulation resistance will decrease unnecessarily. In addition, pay attention to the experimental voltage value of insulation resistance. According to the insulation resistance = the voltage on the insulator, leakage current applied to the different voltage, there is no need of the consequences. In the experiments of connectors, the applied voltages are generally in three levels: 10V, 100V and 500V.

Wire testing machine can not only test insulation resistance, but also can test other data of wire, such as voltage, capacitance, conduction, break short circuit, etc!

Above circumstance, professional personnel should pay attention to avoid.
