Description

The MO2Ke digital low resistance ohmmeter is a portable, microprocessor-controlled instrument used to accurately measure resistances of contacts, switches, transformers and motor windings, etc., using test currents from 1 mA up to 1 A.

It uses the Kelvin-type (4-terminals) measurement principle, thus eliminating errors caused by lead and contact resistances.

Resistance readings are shown in the alphanumeric display with up to a 4½ digit-resolution. It allows to measure resistances of up to 2 kΩ, with resolution of 0.01 mΩ.

Measurements accuracy is guaranteed by the state-of-the-art system for signal-amplification, offset-free and with long-term stability.

The equipment has a serial output (RS232) that allows to collect measured values in a serial printer, notebook or any data logger in order to register the tests performed.

The HOLD function keeps in the display the value measured at a certain time-point.

Test current may be adjusted by the operator in every one of the ranges and their values are displayed in analog form (bargraph), making it easy to measure resistances with a significant inductive component. The open circuit output voltage is up to 10 V, depending on the selected test current, reducing the stabilization time for the test current when highly inductive elements (specially transformers windings) are measured. The measurement circuit has an effective protection against voltage peaks originated by those inductances.

The equipment is housed in a rugged plastic case with a hinged lid and carrying handle. It is a portable, strong, impact resistant and lightweight equipment, suitable to be used in outdoors and under severe weather conditions. It supplies very reliable and accurate measurements both in laboratory and out in the field.
