Note that the resistance is almost five times greater at 68°F (20°C), as<br />
compared to the read<strong>in</strong>g taken at 104°F. The reference temperature for<br />
cable is given as 60°F (15.6°C), but the important po<strong>in</strong>t is to be consistent<br />
and correct to the same base.<br />
