• Megger, Inc.'s Programma Mjolner 200 Microhmmeter is specifically designed for measuring contact resistances of circuit breakers, contacts, disconnect switches, bus-bar joints, and other high current links. The unit is unique in that it offers enhanced testing safety using the patented DualGround^TM technology to test circuit breakers leaving the grounds on both sides in place. The units are high powered, lightweight, and highly portable.
  
  
• From Megger, the DLRO 200-115E is designed to check and measure contact resistance in high voltage circuit breakers, dis connecting switches, and busbar joints. The unit provides test current from 10 amps up to 200 amps and has a filtered direct current output that eliminates magnetic transients. All of this and it weighs less than 33 pounds
  
  
• Megger, Inc.'s DLRO 600 is a digital low resistance ohmmeter that can provide the higher current that is more representative of daily working conditions when testing the contact resistance of high voltage alternating current circuit breakers. The DLRO600 weighs just 32 pounds and has a variable output of 10A to 600A dc in 1A stops. The DLRO600 comes complete with 5m test leads and download software, all at an affordable price.
  
  
• The Megger/Biddle digital low resistance ohmmeters (DLRO) are highly accurate instruments that provide for testing low resistance in the field. The units operate on the four-wire measurement principle, thus eliminating lead and contact resistance.
