EXAMPLE I: 



Assume an initial value of 4200, Since this value lies within the range 

 1000 - 8900, use lower portion of above table. Enter left hand column 

 at 4000, proceed horizontally to the right to column headed 200, and read 

 150. 



EXAMPLE II: 



Assume an initial value of 4180, Since this value is not recorded explicitly 

 in the table, the conversion can be made by one of two methods: 



100
