AJ908 Cable fault tester
1、 Product Description
2、 Advantages and Characteristics:
Domestic leading adoption of industrial control embedded computer platform system, full computer Win7 system operating platform, integrated software testing, and equipped with cable fault testing software.
◆ Leading domestically, it adopts a 12.1-inch large screen, touch mouse operation, high brightness screen display, suitable for outdoor use under sunlight, lithium battery power supply, and convenient on-site testing. Engineering aluminum alloy chassis, shockproof and moisture-proof to achieve strong stability.
Adopting the latest USB communication interface, the collected signal is stable, and the host can automatically select five sampling frequencies from a minimum of 6.25MHz to a maximum of 100MHz. The adaptive pulse width can meet the testing requirements of cables of different lengths, reducing rough measurement errors and improving testing accuracy.
The software enables arbitrary compression and expansion of waveforms, and randomly displays two waveforms that are closer to the standard on the same screen for accurate comparison and analysis. The dual cursor movement can be precise up to 0.15 meters, improving testing accuracy and reducing errors.
The host supports built-in WIFI reception function, and dedicated 3G software can provide expert remote on-site real-time testing technology services at any time. Experts can remotely control the user's host, and the business technology is equipped with mobile Android version testing software, providing users with timely and accurate waveform analysis and communication guidance for on-site testing anytime, anywhere, making your work worry free (optional).
Built in on-site waveform and physical wiring diagram, facilitating on-site testing comparison and daily learning, and capable of automatically generating and printing test reports.
The key precise fixed-point instrument can directly display the distance between the tester and the fault point in digital form. It adopts static noise technology, which is another innovation of similar fixed-point technology in China. It provides strong guarantee for quickly and accurately finding cable faults and reducing power outage losses.
There are four types of high-voltage discharge parts available for users to choose from. The domestically leading new 8.4kg HDG-350+high-frequency high-voltage power supply replaces the 65kg test transformer and operation box. The HDG-251 has an integrated capacitor high-frequency high-voltage power supply high-voltage impact part, which has a wide range of applications and is truly comprehensive and lightweight, leading the domestic market.
