Overview - UNI-T UT267B Operating Manual

I. Overview
UT267 intelligent three-phase digital phase volt-ampere meter (there-
phase digital phase volt-ampere meter) comes out from hard efforts of our
developers and is a fully automatic, multi-purpose, digital and intelligent meter
specially designed for on-site measurement and with following features: high
accuracy, high stability, low power consumption and easy operation. Without
cutting off measured circuits, it can measure three-phase AC voltage and
current, phase angles between voltages, currents or both, frequency, phase
sequence, active, reactive and apparent power, power factor, sum of current
vector; it is able to identify wiring groups of transformers, inductive and
capacitive circuits as well as secondary circuits and bus differential protection
system measurement; it also can read out differential protection phase
between CT units, check and ensure correct wiring of kilowatt-hour meter,
good conditions of wiring equipments, ect, which all together turn this kind of
6
meter a safe, accurate and convenient new electric instrument offered for
electric inspectors.
The meter, designed with latest materials for shell pattern and anti-
vibration, anti-skidding, high-insulation protection jacket, can offer 240dots
160dots and dynamic display together with vector diagram indication, thus
presenting users luxurious and elegant exterior structure. It is equipped with
RS232 and available for data storage of 500 sets which transferred into PC
through system software for further online real-time monitoring, history lookup,
dynamic display, data readout, save, report and printing, ect.
This kind of meter is also known as three-phase digital phase volt-ampere
meter, multi-purpose three-phase digital phase volt-ampere meter, automatic
phase volt-ampere meter, tri-clamp digital phase volt-ampere meter, phase
volt-ampere meter, three-phase electrical parameter tester. It can fully enjoy
functions from intelligent dual-clamp phase volt-ampere meter and general
machinery dual-clamp digital phase volt-ampere meter, which is applied in
