    Megger MJÖLNER 600 Micro-Ohmmeter

    The Megger Mjonler 600 Micro-Ohmmeter is designed for conducting easy, safe and versatile resistance measurements of circuit breaker contacts, supply bus bars, electrical elements and other high current electrical loads.

    Being able to output current between 5A and 600A in 1A steps allows accurate low resistance measurements to be taken, displayed and printed, thus avoiding unreliable test measurements associated with low current testing. Testing can also be conducted inside high-risk, access forbidden areas with the option of a separate remote control, which can be selected from the options above.

    MJÖLNER 600 can also carry out low resistance measurements using the DualGround method. DualGround requires that the test object is earthed on both sides throughout the test period, allowing for a fast and stable measurement. As the DualGround current clamp is an optional accessory, it may be selected from the drop down list above.

    Contained within a strong case, the Megger Mjölner 600 is ready for use in various environments. With the hinged lid closed, the micro-ohmmeter will withstand ingress from water, dust and sand particles and will even float. Resistance measurements can be downloaded to a computer and presented using the optional Mjölner Win PC software, available from the options above.

    Why test resistance at such a low value?

    If the contact resistance on a high current electrical joint is too high, temperature rises and power loss are inevitable leading to a host of problems such as overheating joints and electrical equipment failure. The following table demonstrates the importance of low resistance joins within high current applications:

    CurrentContact ResistancePower Loss 
    10,000A (10kA) 1 milli-Ohm 100,000 Watts (100kW)
    10,000A (10kA) 0.1 milli-Ohm 10,000 Watts (10kW)
    1,000A (1kA) 1 milli-Ohm 1,000 Watts (1kW)
    1,000A (1kA) 0.1 milli-Ohm 100 Watts
