January 2009 UDA2182 Universal Dual Analyzer Product Manual 201
Since the analyzer only allows entry of one wire gauge type, we allow for the worst-case
condition by dividing the total resistance by the resistance per thousand feet of the higher
resistance gauge wire. In our example this would be:
4.0 ohms
÷ 6.4 ohms per thousand feet of 18 AWG wire = 625 feet
Therefore, in our example we would use the procedure in Table 6-5, and specify the wire
gauge as 18 AWG and the length as 625 feet.
