The EMF (Electromagnetic Field) measurement at the highest level component for the sample with a 30cm measuring distance was shown as below: 1 c: S5 ?3 w! q+ ^- U
Weighted Result (W) Limit Pass/Fail

( Q: F4 `' `' tNotes: The weighted result is obtained from the sum of the frequency components using the following formula: W = a*r*B1/B2 $ L t1 j" n) n* O
Where 9 F' u. s; U. f4 ?2 ~* k
W is the weighted result; * E/ k6 I* h3 }2 t9 L, Y" }
B1. is the r.m.s. value of the magnetic flux density; - U( @3 r, w8 b: O/ `
B2 is the reference level of the magnetic flux density at 50Hz;
: j2 u8 ^, [- T& u3 Da*r is the coupling factor. |
