CEM DT-5520 Insulation Tester

CEM DT-5520 Insulation Tester

The CEM DT-5520 Insulation Tester is a robust and reliable instrument designed for precise evaluation of electrical insulation and continuity in various installations and equipment. This device is particularly valuable for electricians and technicians engaged in ensuring the operational safety and integrity of electrical systems.

Key to the CEM DT-5520’s functionality is its provision of a 1mA test current for the MegOhm range at the rated voltage. This specific feature allows for accurate measurement of insulation resistance, which is critical for diagnosing the health and longevity of electrical insulations. By delivering a consistent 1mA current, the tester ensures that high resistance values are measured accurately, helping professionals identify potential insulation breakdowns that could lead to dangerous electrical faults.

In addition to its insulation testing capabilities, the CEM DT-5520 is equipped with a powerful 200mA short current for testing continuity. This high level of current is essential for thoroughly checking the continuity of circuits and connections within electrical systems. The 200mA current strength is particularly effective for identifying any discontinuities or faults in wires and connections, which are crucial for maintaining the safety and efficiency of electrical installations.
