When the 'Repeatability' clause in EN61000-3-2:2000 (clause 6.3.2.1) is applied, is the comparison value (reference value) the result from another test run, or is it the test limit?
For example, the harmonic test limit is 300mA, and the values from two test runs are 7.4mA and 13mA. 1) If the comparision value is from the other test run: 13mA-7.49mA -----------*100=42.4% (failing the test) 13mA 2) If the comparison value is the test limit: 13mA-7.49mA -----------*100=1.8% (passing the test) 300mA Method 1 seems overly stringent, but I can't find anything in the standard covering the method. Is this detail covered in another standard (like 61000-4-7?) --- Pat Lawler pat dot lawler at verizon dot net This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
