Multipurpose low / high resistance meter MIKO-2.3

MIKO-2.3 is a portable mini-laboratory allowing performing of all tasks connected with resistance measurement in electrical equipment as this instrument operates in four modes: micro-ohmmeter, milli-ohmmeter, kilo-ohmmeter and thermometer.

Overview

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

 

Key Features

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

Micro-ohmmeter

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

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

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.

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