10a Digital Micro Ohmmeter

We are offering our customers a wide range of 10A Digital Micro Ohmmeters, which are available in various sizes and specifications. The MPK-2000e digital very low resistance ohmmeter is a portable, microprocessor-controlled instrument used to accurately measure resistances of switches and circuit breaker contacts, transformer and motor windings, wire and cable samples, joints in busbars, etc. using test currents from 1mA up to 10A. It uses the Kelvin-type, four-terminals measurement principle, thus eliminating errors caused by lead and contact resistances.

Resistance readings are shown in the alphanumeric display with up to a 4A digit-resolution. It allows to measure resistances of up to 200W, with basic accuracy of 0,10% and resolution of 0,1mW. 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 (RS-232) that allows to collect measured values in a printer, lap-top, palm-top computer, 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. The open circuit output voltage is of up to 10V, 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.
