Enter the values in the appropriate table below.For A(8)i values:Square and add the A(8) ivaluesSquare-root the result to give the dailyvibration exposure A(8).A i(8)A i(8) 2Exposure 1 Exposure 1Exposure 2 Exposure 2Exposure 3 Exposure 3Exposure 4 Exposure 4Exposure 5 Exposure 5∑A i(8) 2 = n = ∑n i=For n ivalues:Add the score values to give a totaldaily points, nUse the centre scale to convertthe n value to A(8)n i2140A(8) = ∑A i(8) 2 = A(8) =
