TDR-410 OPERATING MANUAL    version 1.03 

1  Introduction 

A time-domain reflectometer (TDR) is an electronic instrument used to characterize and locate faults 
in metallic cables.  
The TDR-410 is a hand held Time Domain Reflectometer with 11-range-scale covering the range 0-
4000  meters,  with  a  7  meter  first  range  scale  and  a  0.5  meter  dead  zone  close  and  far  faults  are 
clearly displayed on its 128x64 pixel back light LiquidCrystalDisplay. 
The Auto Fault Location key will move the cursor directly to the first event or fault, thus  it eliminates 
the  need  to  interpret  visiually  the  form  of  wave.  When  set  in  manual  mode,  the  wave  form  may  be 
scanned  visually  as  on  conventional  TDRs.  In  both  modes  the  user  gains  variably  coverage  of  the 
range  of  default  to  64  db's  used  to  magnify  small  events  identified  on  the  waveform.  The  scan lock 
feature will allow the user to hold the trace for closer examination. 
Designed for identifying and locating faults on all metallic cables with two or more insulated conduc-
tors. The TDR-410 has impedance matched circuits for 25, 50, 75 and 100 ohms and with velocity of 
propagation  settings  from  1-99%  (or  the  equivalent  in  feet  or  meters/micro  second)  will  cover  the 
range of power, data, communication and CCTV cables. 
Housed in a rugged IP54 rated ABS enclosure and weighs only 350 grams (12 ounces), theTDR-410 
is suitable for outside use. 
 

 

 

   

NOTE!  

Only standard and additional accessories for a given device should be used, as listed  

in the "Equipment" section. Use of different accessories can lead to errors in the test  

connection and can introduce additional measurement uncertainties.  

 

 

 

Note:  

Due to continuous development of the meter’s software, the actual appearance of the 

display, in case of some of the functions, may slightly differ from the display presented 

in this operating manual.  

  

 
 

 

Warning:  

 

This instrument meets the safety requirements of IEC 61010-1:1995 

 

TheTDR-410 is designed for use on de-energized circuits only. 

 

Connection to line voltages will damage the instrument and could be 

hazardous to the operator. 

 

This instrument is protected against connection to telecom network voltages 

according to EN 61326-1. 

 

Safety is the responsibility of the operator
