Product Description

Programma MJÖLNER 200 Microhmmeter

The MJÖLNER is designed to measure the resistance of circuit breaker contacts, bus-bar joints, contact elements in bus-bars and other high-current links. This product is designed with safety, ease of use and versatility in mind.

The micro-ohmmeter can be used anywhere to measure a low resistance value with high accuracy. It conducts true DC ripple free current testing of bus bars, circuit breakers, fuses, etc.

With MJÖLNER 200 it is possible to make measurements according to the DualGround* method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow.

• Specifically designed for measuring contact resistances of circuit breakers, contacts, disconnect switches, bus-bar joints, and other high current links
• Safer testing using the patented DualGround™ technology to test circuit breakers with both sides grounded
• Fully automatic testing- microprocessor controlled
• Ability to store test results
• Built in thermal printer
• PC interface connection
• Wide measuring range and test currents
• High-power and lightweight

The MJÖLNER 200 Microhmmeter is used as follows:

Circuit Breaker testing

• Test of circuit breaker contacts
• Test of the connections to the breaker

Testing of Bus-bar

• Test of Bus-bar joints
• Test of connections

Transformer testing

• Winding resistance – not on all type of transformers. (In many transformers there is a need for higher voltage than 5 V.)
• Internal/external connections

Everywhere you need to test a low resistance/ high current connection

• Switches
• Disconnecting devices
• Safety ground connections
• Welding points
• Fuses
• Cables
