Features
Communication Function
- Equipped with a WIFI module and a SIM interface.
- Enables remote data transmission and technical support.
Waveform Display
- 3-zone display on the same screen, randomly showing 10 measured waveforms.
- Both automatic and manual processing modes, and can store, playback, and analyze the waveforms.
APP Support
- The Cable Quick Test APP provides services such as remote waveform analysis, case sharing, teaching and training, and simulated exams.
Unique Design
- The multiple pulse method generator can obtain 10 low voltage short-circuit pulse waveforms with a single discharge, and automatically select the optimal standard waveform, reducing interference.
- Precise Cable Fault Pinpointing:
- The Cable Fault Pinpointing System uses the dual-selection technology of noise suppression and filtering. It digitally and synchronously displays the distance change between the test point and the fault point, and can detect the cable route.
- APP and Bluetooth connection allows two people to locate the fault point simultaneously.
Hardware Design
- Adopts a large 12.1-inch screen. The high-brightness LCD is suitable for strong outdoor light.
- Powered by a lithium battery.
- Engineering plastic case is shockproof and moisture-proof, ensuring strong stability.
Testing Performance
- The main unit automatically selects eight sampling frequencies ranging from 3.125MHz to 400MHz, and has an adaptive pulse width to meet the testing requirements of different cables.
- The software can automatically identify the inflection points of the testing waveforms in the low voltage pulse method, impulse flashover current method, and multiple pulse method, and automatically read the fault distance.
