II. Product Features

◆ Adopt12.1inLarge touch screen, rotary mouse control, high-bright LCD display, suitable for outdoor use in sunlight, lithium-ion battery-powered, convenient for on-site testing. Engineering plastic housing, shockproof and moisture-proof, with stability.

◆ Utilizing the latest integrated communication technology, signal acquisition is stable, and the main unit can automatically select the *lowest* level.6.25MHz、*As high as200MHzSix sampling frequencies, adaptive pulse width, to meet the testing requirements of cables of various lengths, reducing predictive errors and enhancing testing accuracy.

◆ The software automatically identifies and searches for low-voltage pulse and multi-pulse wavefronts, automatically locates the fault point on waveforms, reads and displays the fault distance.,Triple Area Waveform Display on the Same Screen, Ten measured waveforms are randomly displayed on the same screen for selection, while simultaneously achieving both automatic and manual processing modes.,Achieves dual positioning operation on the waveform, with both cursors moving to0.15Rice, improved test accuracy, reduced waveform error.

◆ Unique multi-pulse generator design,No wiring conversion needed on-site to complete the three-mode testing.Please try,And a single discharge yields a waveform of ten low-voltage short-circuit pulses.,Greatly reduces the interference of large oscillations; the multi-pulse generator is compact in size, weighing only5KGAchieve true lightweighting for the entire equipment set.

◆ Main unit is expandable5GWith technologies like Bluetooth, experts can provide real-time on-site testing services remotely at any time. They can remotely control the user's host, offering timely and accurate waveform analysis as well as guidance and communication on-site, ensuring the user can work without worries.

◆Built-in actual waveform and test实物 connection diagram, facilitating on-site testing comparison and daily learning, capable of automatically generating test reports for printing, and can be used as cable operation and maintenance records.

◆The positioning instrument section can directly digitally synchronize and display changes in the distance between the test points and fault points. It simultaneously detects the cable path direction, enhancing positioning efficiency. Employing noise reduction filtering technology, it provides a robust guarantee for quickly and accurately locating cable faults, thereby reducing power outage losses.

◆Path function detection and signal integration are incorporated into the master and slave units of the fixed-point instrument, making on-site use convenient and quick.
