The tester is designed with high-speed microprocessor and 3.5-inch color touch-
screen LCD, enabling smart touch operation and easy use, it can display the value
and waveform of measured current in real time. With FFT, digital filtering and other
technologies employed, the tester makes measured data more accurate. UT279
has multiple functions such as alarming threshold setting and warning indication,
data & time and "Setting", auto power off, setting of numbering of tested object, it
is able to save 200 sets of data and waveforms, the stored data can be imported
to computer via the USB interface of the tester.
As the iron core of current clamp is made with permalloy and magnetic shielding
technology, it is not susceptible to influence and interference from external
magnetic field, ensuring continuous measurement of high accuracy, stability and
reliability. The internal diameter of the clamp jaw is 80mm×80mm, which allows it
to clamp cable or grounding wire of 80mm below, or 96mm×4mm grounding wire
of flat steel. The clamp jaw features portable design and realizes non-contact, safe
and rapid measurement without the circuit under test disconnected.
The monitoring software has multiple functions such as on-line monitoring in real
time, data viewing, data storage, data printing, dynamic display, waveform
indication, alarming threshold setting, alarm indication, and more.
