Frequently Asked Questions
Is the Megger MIT410/2 insulation and continuity tester suitable for testing low voltage cables?
Yes, the MIT410/2 tester, with low test voltages like 50 and 100 volts, is suitable for testing low voltage cables and sensitive equipment to avoid damage to delicate insulation.
What is the difference between the insulation resistance index (PI) and the dielectric absorption ratio (DAR)?
The insulation resistance index (PI) is the ratio of insulation resistance measured over 10 minutes to the resistance measured over 1 minute and is used for detecting moisture or deep contamination. The dielectric absorption ratio (DAR) is the ratio of resistance measured over 60 seconds to the resistance measured over 15 seconds, used for quick evaluation of surface moisture in insulation.
Does this device have the capability to connect to a computer?
The MIT410/2 model typically lacks direct connectivity to a computer; however, test results can be manually recorded. Higher models in the MIT series may offer additional connectivity options.
