1. Description
The MEGABRAS MPK203x is a smart and portable digital ohmmeter. Has
optimized filters and protections for measurements in electrical substations. Can be
used to accurately measure very low contact resistances of high voltage circuit-
breakers and switches, busbars, etc., with test currents up to 200 A. It employs the
4 terminals-method (U/I measuring principle) to avoid errors caused by test leads
and their contact resistances.
Measurement accuracy is guaranteed by a state-of-the-arts signal amplification
system, offset-free and of high long-term stability. Resistances readings are shown
in the alphanumeric display with up to 4½ digits-resolution.
Test current may be adjusted by the operator and his value is measured using an
analogue indicator (bargraph).
It has an internal memory for up to 200 readings. The serial data output (USB) may
be connected to a computer to download the stored values.
The high-current generation system is based on modern technology that allows to
significantly decrease both its weight (approx. 11kg) and size. The cabinet is made
of plastic material highly resistant to impacts and to environmental challenges.
Internal thermal sensors in all sensitive components avoid any damage caused to
the instrument due to overheating.
This is a strong but lightweight equipment, and may be easily carried by one
person. It is waterresistant and can be used under severe weather conditions (IP54
with closed lid) offering an excellent performance working both in the laboratory
and out in the field.
