Receiving Your Shipment Upon receiving your shipment, make sure that the contents are consis- tent with the packing list. Notify your distributor of any missing items. If the equipment appears to be damaged, file a claim immediately with the carrier and notify your distributor at once, giving a detailed description of any damage. -
Page 7: Product Features
CHAPTER 2 PRODUCT FEATURES Description The Fault Mapper is a handheld, Alpha-Numeric, TDR (Time Domain Reflec- tometer) Cable Length Meter and Fault Locator, which is designed to measure the length of power and communication cables or to indicate the distance to a fault on the cable, given access to only one end. By incorporating Fast-edge Step TDR Technology, the Fault Mapper measures cable length and indicates the distance to open or short circuit faults, to a range of 6000 ft (2000m) on at least two conductors. -

Page 10: Operation
CHAPTER 4 OPERATION Principles of Operation The Fault Mapper works by measuring the time taken for a signal to travel to the far end of the cable under test, or to an intermediate fault and return. The velocity at which the signal travels, or Velocity of Propagation (Vp), will depend on the characteristics of the cable. Based on the selected Vp and the measured travel time of the test pulse, the Fault Mapper calculates and displays distance. Accuracy and Velocity of Propagation (Vp) The Fault Mapper measures distances to faults and cable lengths to an accuracy of ±... -
Page 11: Getting Started
Getting Started The instrument is switched on and off using the green power button found on the lower right side of the front panel. When the unit is first switched on it will display the opening screen giving the software version, the currently selected cable type/Velocity of Propa- gation, and remaining battery capacity. AEMC Instruments Fault Mapper V3.1B Romex 14/2 Vp=66% Set-up Mode Hold the button, then press the button to enter Set-up mode. TDR / TEST / > Feet Eng (USA) -

Programming a Custom Library Location To program a custom library location, enter the Set-up mode (see § 4.4). Press the button to select Edit Library; the line selector (>) should TEST / be at Edit Library. Press the button to enter the library programming mode. • The Model CA7024 will display the first programmable cable loca- tion in the library. • The factory setting for each location is Custom Cable X with a Vp = 50%, where X is location 1 through 15. -

TDR / Backlight The display backlight is switched on and off with the button. Tone Generator The Fault Mapper may also be used as a tone generator, to trace and identify cables and wires. The user will need a cable tone tracer, such as the AEMC Tone Receiver/Cable Tracer Model TR03 (Cat. #2127.76) or equivalent. Fault Mapper Model CA7024 0.561.8187 information@itm. www. .com... -

When set, the following will be displayed: * * * * * * * * * * * * * * * * * * * Warble Tone * * * * * * * * * * * * * * * * * * * The injected signal oscillates between 810Hz and 1110Hz, six times per second. -
Page 15: Determining And Measuring Vp Values
Determining and Measuring Vp Values Velocity of Propagation (Vp) values are characteristic of each cable type and brand. The Vp is used to measure the length of a cable and to measure a fault location. The more accurate the Vp, the more accurate the measurement result will be. -

Vp will be displayed with a value, which can be selected from 1 to 99%. If the Vp value is not known, see § 4.9. AEMC Instruments Fault Mapper V3.1B Vp=95% NOTE: When the Fault Mapper is turned off, it will remember the last selected Cable Library or Vp setting. This feature is useful in the situation where the operator is performing many tests on the same type of cable.

Page 18: Attaching A Cable To The Fault Mapper
4.11 Attaching a Cable to the Fault Mapper 1. Make sure that there is no power supply or equipment attached to the cable to be tested. 2. Check that the far end of the cable is either open or shorted (not fitted with a resistive termination). 3. Attach the Fault Mapper to one end of the cable to be tested. The cable attachment is via a BNC connector located at the top of the unit. For unterminated cables use the alligator clip attachment provided. -
Page 19: Measuring Cable Length Or Fault Distance
Assuming there are no opens or shorts in the cable, the length of the cable will be displayed. For lengths less than 100ft, the displayed value will be to one decimal place. AEMC Instruments Fault Mapper V3.1B Open Circuit 63.2ft For lengths over 100 ft the decimal place is suppressed. -
