Compact micro-ohmmeter MIKO-10 is designed for easy measurement of the DC electrical resistance using a current of 1 A / 10 A.

Applications include:

- contacts of high-voltage circuit breakers (including with built-in current transformers);

- connecting or disconnecting switches, busbars, wires and cables;

- bolted, riveted, welded and brazed joints, aircraft skins, etc.

The instrument has 3 start modes for the measurement process:

·        AUTO: is designed to measure the contact resistance of high ­voltage circuit breakers without current transformers and any demountable or non-demountable connections with current of 10 A. The measurement starts automatically when the test cables are connected;

·        SINGLE: is designed to measure the contact resistance of high-voltage circuit breakers without current transformers and any demountable or non-demountable connections with current of 1 or 10 A.

·        BUILT-IN CT: is designed to measure the contact resistance of high-voltage circuit breakers with built-in current transformers.

The instrument is applied in electric networks, power plants or substations, traction substations of electrified transport, as well as in industrial enterprises.

The instrument has a number of important additional functions that meet the latest user requirements:

- 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;

- Sounds an alarm at the start and at the end of the measurement.

The operating temperature range from -20°C to +55°C allows working with the instrument in difficult weather conditions, while the stated accuracy of the results is guaranteed.

PC connection via USB allows managing and saving results on a PC or laptop, and generating measurement reports.

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.

The built-in battery of MIKO-10 provides portability. One battery charge is sufficient for 1000 measurements or more at maximum current.

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