  • TDR and Bridge Cable Fault Locator

    ST620B - Shandong Senter Electronic Co., Ltd

    I.OverviewThis DMM/TDR cable fault locator is the latest generation cable tester, which is designed with the technology of ARM+FPGA large dot matrix color LCD display . It is used for the measuring of exact fault location such as the broken line, cross faults, earthing, poor insulation and poor contact of the lead covered cables as well as plastic cables. It is an effective tool to reduce troubleshooting time, improve work efficiency and reduce labor intensity of line maintenance staff. It also can be used in line projects acceptance and inspection of electrical cableII. Features1. Large color LCD Display (480 x 280 dot); humanized operation interface; six function keys and simple operation.2.Combine with pulse reflection testing (TDR) and Digital Multimeter(DMM), can test broken lines, crossing lines, poor insulation and other types of faults.3. Manual testing function is preserved.4.Full English Menu is easy to master and use.5.With megameter and ohmmeter, it enables to test insulation resistance and loop resistance.6.With USB Port, it is easy to upload testing data to computer(This function is optional)7 Rechargeable lithium battery, intelligent charging without duty.8.Small dimension, light weight and portable design.Specifications1)Pulse reflection testing(TDR)Max range: 8 km(16kms, and 32kms are optional) Dead Zone: 0 mTesting Accuracy: 1mPulse width: 40ns-10μs with automatic adjustment Automatic impedance balance adjustment Automatic and manual gain adjustment2) Digital Multimeter(DMM)DC voltage: -400V~ 400V, resolution can reach 0.001VAC voltage: 0V~290VCapacitance: 0nF~1000nFAccuracy: 0--10nF: ±2nF; 10nF--1000nF : ±2% +±2 nF Loop resistance: 0Ω~20kΩAccuracy: 0--100: ± 3% +± 4Ω 100- 500: ±3% ; 500-20 KΩ ±2%Insulation resistance between line: 0M Ω -30M M Ω.Accuracy:0--1.0M: ±0.1M Ω 1.0M - 30M: ±10% + 0.5 MΩ.The charging time of about 3.5 hoursFull - after 8 hours of continuous operating timeSize: 210mm * 166mm * 90mmWeight: 1KgAccessories:1) Carry case.2) Re-chargeable battery and charger/adapter.3) Test Line4) User Manual5) CD (Just for USB function)6) U-disk (Just for USB function)
