Hello,
My company has been trying unsuccessful in passing precompliance testing conducted immunity (61000-4-6). We are prepping up for our 3rd attempt.
The product is an electronic weight scale the stated accuracy in the manual is 0.2% . The output is a LCD display showing weight.
During the conducted immunity testing the output of the scale went well outside the stated accuracy. After the test no intervention is required (the displayed weight error goes away when the test is complete) thus, the degradation of performance ceases after the disturbance ceases and there is full recovery to normal performance, without operator intervention.
Is it possible to fail the conducted immunity testing (Criteria Level A) at various frequencies but yet still be able to move forward by utilizing Criteria Level B?
where
Criteria level A: normal performance withing equipment specifications
Criteria level B: degradation or loss of function or performance which is self recoverable when the interfering signal is removed.
Criteria level C: degradation or loss of function or performance that requires system reset or operator intervention when the interfering signal is removed.
It sounds straight forward.... (thus written into the spec, thus in answering my own question .... YES)...
I am assuming that it would have to be clearly stated in the Guidance and Manufacturers Declaration contained in the manual....
Are there any pitfalls that I should watch out for if going with Criteria Level B that I am missing?
I look toward your response,
