Compact wrist-wearable micro-ohmmeter MIKO-10 is designed for instant DC resistance measurements within the range 1 μΩ - 0.1 Ω.

MIKO-10 enables measurements at following objects:

  • High-voltage or auto circuit breakers;
  • Releasing, connecting or disconnecting switches, contactors and relays;
  • Bolted, welded and brazed joints of current leads and busbars;
  • Rail connections and wagon wheel pairs;
  • Electric motors, generators, compensators, and other objects. 

MIKO-10 is ahead of similar instruments represented in the market due to a number of functional and technical features.

MIKO-10 is applied in electric networks, power plants or substations, traction substations of electrified transport, as well as in industrial enterprises where 10 A test current is sufficient for measurements.

In turn, test current in similar instruments does not exceed 2 A, so that MIKO-10 (with test current up to 10 A and the weight of 0.5 kg) achieves leading positions among micro-ohmmeters of this class.

In case of obvious oxide film on the contacts more powerful micro-ohmmeters are recommended, such as MIKO-21 (test current up to 200 A) or MIKO-2.3 (test current up to 1000 A), as measurements using low currents in such instances can show higher values of resistance and, as a result, the contacts may be unjustifiably rejected.

Different measurement modes are implemented in the instrument:

AUTO: is intended for contact resistance measurement of HV circuit breakers w/o CT and any demountable or non-demountable connections with test current 10 A. The measurement starts automatically by the circuit closing;

SINGLE: is intended for contact resistance measurement of HV circuit breakers w/o CT and any demountable or non-demountable connections with test current 1 A or 10 A. The measurement starts by the User command;

BUILT-IN CT: is intended for contact resistance measurement of HV circuit breakers with CT with test current 10 A. The measurement starts by the User command.

MIKO-10 is a modern compact micro-ohmmeter that meets the latest user requirements.

The instrument has a number of important functions:

  • Auto thermal EMF balancing in the test circuit;
  • Auto power off, if the instrument is not used;
  • Circuit continuity test;
  • Auto measurement start against the test circuit continuity confirmation;
  • Sound alarm at the start and at the end of the measurement.

One battery charge is enough for at least 1,000 measurements at maximum current.

The instrument has an energy independent memory of up to 100 recordings that is sufficient for overall and complex test of the substation.

USB connection to the PC facilitates classification and storage of the measurement results and generation of the reports.

Special software developed by the manufacturer is used for data transfer from the instrument to the computer and for measurement results archiving.

The built-in battery of MIKO-10 makes the operation process fully self-contained. One battery charge is enough for more than 1,000 measurements at maximum current. Energy independent memory up to 100 recordings ensures a complex test of a substation.

MIKO-10 can justly be referred to portable instruments due to its light weight of 0.5 kg and small dimensions 165 × 100 × 60 mm.

The above peculiarities ensure complete autonomy of the instrument over the vast territory of substation or facility.

MIKO-10 is enclosed in an ergonomic case that can be placed on the arm and secured with fastening straps, with both hands free to simplify the measurement process.

Also, the instrument can be easily removed from the arm and fixed to a belt or your neck, or placed on any flat surface.

There are specially designed cables of different length and with different lugs for reliable connection to the measurement object.

Additional items to be purchased:

  • Kelvin double hand spike test cables. For instance, these cables can be used to test the resistance of busbars and terminal buses;
  • Kelvin clamp test cables;
  • Kelvin type test cable with probes and crocodile clips
  • Protective case;
  • Universal belts;
  • Wearproof tool bag.

High accuracy of results is ensured even for diagnostic in heavy weather conditions. MIKO-10 operation is guaranteed at a temperature range from -20°С to +55°С.
