Page 5: Brief Introduction
BRIEF INTRODUCTION This Cable Fault Locator (hereafter referred as locator) can measure the 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. The highlights for this locator are that it can test numbers of typical faults, features are as follow: 1) Digital gain Adjustment control to make the gain adjustment very easy. -
Page 6: Specifications
SPECIFICATIONS Max range: 8 km (2km/4km/16km/32km are optional) Highest resolution: 1m Dead Zone: 0 m Power consumption: 1W Weight(kg): 0.38kg Dimension(mm): 204×100×36mm Working temperature: -15℃ to + 45℃ Storage temperature: -20℃~ + 55℃ USB storage (optional): transmit wave form to U disk, and analyze the wave form on computer. -
Page 7: Working Principle
WORKING PRINCIPLE Pulse testing is a kind of remote testing method; one can locate the fault point without testing on the field or testing with end-to-end coordination. The principle of the theory is: The instrument emits a pulse to the line, when the line has faults, the pulse reflection will change. -
Page 8: Testing Procedures
TESTING PROCEDURES Diagnosis of fault characters To insure the accuracy of the testing of fault point, the testing personnel shall diagnose the fault characters correctly and then choose the most suitable testing mode. The characters of telecom cable faults can be simply divided into the following several kinds: Broken line One or many cable core line are broken. - Page 9 low communication quality or even blocks. Bad insulation The insulating resistance between different couple of lines and the core drops to a very low level, the communication quality comes under serious influences. Fault Testing Cut off the cable to be tested both sides lines or equipment. Make sure the cable to be tested is free of voltage.

AUTO TEST Press , connect the testing lead line and fault cable line. Press and then the instrument will show the testing result. Note: The default setting wave velocity is 200m/μs, when you perform intelligence testing, the user shall check whether need to adjust the velocity. - Page 11 2) Range During manual testing, range decides the maximum testing distance of the instrument, so the range value shall be chose as longer than actual length of the cable to be tested. To adjust the Range, press , until Range shows reverse color display.
- Page 12 inflection of the reflected waveform. The fault distance will demonstrate on the underneath of the display screen. 4) Waveform Comparison (Optional) Press until it displays “Press “-” to memory, “+” to both”. Now press “ ” to save the current waveform; press to call the original out and compare with the current waveform.
- Page 13 the current cable. After test is finished, if you want to save file, you can press until "Press “-“ to quit, ”+” to save" appears. Under this condition, press to normal testing mode; press to save the current file to U-disk. Check and analyze the previous wave files Press until it displays “Press “-”...

Page 16: Charging
CHARGING Current battery power is showed at the top-right of the screen. If the battery power is inadequate, please use the instrument charger to charge it. The indicator light of the charge adapter will be red when charging; and it will turn green after it’s fully charged. ATTENTIONS Keep display screen away from direct sunlight.
