MIKO-2.3 is a portable mini laboratory designed to measure the DC electrical resistance and temperature of different parts of electrical equipment, as it is operated in four modes: micro-ohmmeter, milli-ohmmeter, kilo-ohmmeter and thermometer.

Micro-ohmmeter mode is designed to measure the contact resistances of any switching devices, as well as demountable and non-demountable contact connections. In addition, this mode allows taking into account the presence or absence of a current transformer in the measured circuit ("CT-yes", "CT-no", "CT-yes Tmax").

Milli-ohmmeter mode is designed to measure the DC electrical resistance in circuits containing inductive equipment (transformers, electromagnets, electric motors, etc.) In addition, there are two measurement sub-modes: one-phase and three-phase winding resistance measurement, and automated recalculations.

Kilo-ohmmeter mode is designed to measure the resistance of ballast, shunt, additional and other resistors with induced voltage up to 5 kV, as well as without induced voltage.

Thermometer mode is designed to measure the temperature of oil, water, air and, other non-aggressive environments.

Identification of each of the four modes is automatic by connecting the corresponding test cable.

With a weight of only 2.7 kg, the instrument produces a current of up to 1000 A, which has no equals in the market (the instrument which is closest in terms of functional capabilities runs with a current of up to 600 A and has a weight of 7.5 kg, with power supplied from mains).

In addition, currently there are no other instrument that combines the functions of four devices in one.

Due to a combination of functional and mass-dimensional parameters MIKO-2.3 achieves cutting edge innovation, while the above features and self-contained power supply ensure full portability and high mobility of the instrument over the vast territory of substation or facility.
