Loop resistance test 

Use resistance test function can determine the length of cable. 
Conversely, if you know the length of the cable, the resistance 
test  result  will  show  whether  the  cable  connection  is  good  or 
not.  
Calculation formula: L=R

L

/R

①

: RL is resistance measurements result (Ω), RO is the 

resistance (Ω) per kilometer.  
General specifications for the 0.32 mm copper RO = 435.2 Ω 
specifications for the 0.4 mm copper RO = 278.5 Ω 
specifications for the 0.5 mm copper RO = 178.3 Ω  
If  the  course  of  testing  equipment  tips  “out  of  range”  which 
shows  test  nips  not  connected  or  cable  not  looped  or  out  of 
resistance  range,  please  check  the  test  nips  or  retest  after 
loop the cable again. In the test, if there is in voltage (voltage 
more than 2V) in the line, then there will be a prompt “voltage”.  
It  means  this  line  have  electricity  and  cannot  test  the 
resistance.  Please  check  the  lines  and  test  after  cutting  the 
electricity.  Please  see  picture  for  loop  resistance  calculation
