According to the input parameters the unit will display the resistance value for a distance of 1 km.
i.e. :
A measured resistor of 220 ohms on a 100 meters long cable , the value for 1 kilometer will be :
1km/100m x 220 ohms = 2200 ohms
A measured resistor of 220 ohms on a 2000 meters long cable , the value for 1 kilometer will be :
1km/2km x 220 ohms = 110 ohms
A measured resistor of 220 ohms on 2 parallel 100 meters long cables , the value for 1 kilometer
will be : 1km/100m x 220 ohms x 2 = 4400 ohms
A measured resistor of 220 ohms on 2 series 100 meters long cables , the value for 1 kilometer will
be : 1km/100m x 220 ohms / 2 = 1100 ohms
NOTA : the ohm per km value will be displayed in big characters and the true value will be displayed
in small characters ( Rx= 220,00 ohm)
km :
Press on [km] to select the resistance display in kilometers.
 Press on [ No. ] to modify the number of cable connected in series or parallel
o Enter a number between 1 and 99 with the numeric keypad
o Press on [OK] to enter the value
 Press on [ Res ] to modify the resistor per distance unity (km or meter)
o Enter the value according to unity with the numeric keypad
o Press on [OK] to enter the value
 Press on [ Unit ] to select Meter or Kilometer
o Press on [ meter ] or [ km]
o Press on [OK] to enter the selection
 Press on [ Conn ] to define if the cables are series or parallel connected .
o Press on [ Ser ] or [ Par ]
o Press on [OK] to enter the selection
 Press on [OK] to go back to the previous page
 Press on [QUIT ] to escape the menu .
According to the input resistance per meter or kilometer value the unit will display the length of the
cable .i.e. :
A resistor per kilometer of 220 ohm x km on 1 cable with a measured resistance of 220 ohms , the
cable length value will be :
220 ohms / 220 ohmxkm = 1 kilometer
A resistor per kilometer of 220 ohm x km on 2 series cables with a measured resistance of 220
ohms , the cable length value will be :
220 ohms / 220 ohmxkm /2 = 0.5 kilometer
A resistor per kilometer of 220 ohm x km on 2 parallel cables with a measured resistance of 220
ohms , the cable length value will be :
220 ohms / 220 ohmxkm x 2 = 2 kilometer
NOTA : the km value will be displayed in big characters and the true value will be displayed in small
characters ( Rx= 220,00 ohm)
