1Micro-Ohmmeter Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, this igital micro-ohmmeters are designed for simple, safe and efficient testing of:

• disconnecting switches,

• high-current bus bar joints,

• cable splices,

• welding joints,

• and different high-current links in factory and high-induction field environments.

All micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).

Starting from 2003, This has been a trend-setter on the market when our first 500 A micro-ohmmeter weighing only 8 kg was released.

Currently, products portfolio includes 16 models, divided into 3 series:

• 13 portable models.

• 6 handheld models.

The instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.
