2 .4 Measuring Capabilities 



Rope Size and Construction 



All steel wire ropes of any construction from 1/2 to 



2 1/2 inches in diameter (12-64mm) . 



Rope Speed 



0-600 ft./mln. (0-3 m./s.) with 300-400 ft./mln. 



(1.5-2.0 m./s.) as a preferred testing speed 



Sensitivity 



LMA - + .57o change in metallic area 



LF - a discontinuity of .1% of nominal rope metallic 

 area 



Accuracy 



LMA - + 2.57o of reading for all rope sizes and con- 

 struction from 0°c to +30°c 

 + 5.7o of reading from -20°c to +40°c 

 LF - peak signal repeatable with +57o accuracy from 

 0°c to +30°c and + 107o accuracy from -20°c to 

 +40°c . 

 Accuracy specifications are referenced to readings at 

 +20°c . 



Detecting Length 



Metallic area reduction/increase will be detected with 

 the accuracy specified provided they exist over a length 

 of 24 inches (610 mm.) .
