Main features: compact and lightweight handheld device, touch screen + button operation cable tester to check the type of barrier, approachable and easy to use. Single fiber through a single fiber or distal beat loopback test to target cable. Strong ability to field applications check the cable barrier device, to meet user demand for burial, to pinpoint the target cable conduit cable census or cutover time. Can monitor the mechanical vibration of the distal end of the cable. In a complex environment through audio or visual signal to target cable; have a stronger ability to adapt to the environment, especially when the fiber under test conditions, such as when a fracture line check cable barrier principle instrument can accurately find the fiber under test; Also check the cable barrier model number, line investigation in the cable end of the line for the APC connector, DY800 can easily find the target cable. Cable identification is important in cable construction and maintenance work. At present, there are blackout cable identification and cable identification device charged cable identification device two kinds. The live cable identification device combines power cable identification device functions. Power cable identification device commonly used method is the pulse polarity. How it works: to be recognized cable plus a special signal, the receiver with the receiver, use this feature to find the cable will be able to identify (to be identified due to a cable outage, can be directly added to the signal, the test is simple, the principle will not repeat ). Check cable fault tester supply, check the cable barrier device, provided by the Tianjin Xin Xin Hao Yuan Hao Yuan Science and Technology Development Co., Ltd. Tianjin Xin Hao Yuan Science and Technology Development Co., Ltd. (tjaic.gov.cn/shownews.asp?id=5921) strong, credible, in Tianjin's special instrumentation industry has accumulated a large number of loyal customers.
