When you, being the "relay manufacturer", do not disclose as a reply to statemets from me like Does 'the management' really believe that a relay manufacturer when it is known to you that 'the management' is the 'relay manufacturer'.

I can see no other reason for hiding this fact than trying to make Kai and I, who only want to help, look like fools. It is very rewarding to be made look like a fool for trying to help someone.

Suresh, I hope you had fun, since the hidden fact has made everyting posted irrelevant, so if you did not have fun the whole thing is wasted. Of course if it was ment as a (bad) joke, the joke is on Kai and I.

Next time choose up front if you want advice, in which case you disclose everything If what you want is to make a mockery out of whoever will be volunteering help for free, by all means you should not disclose anything relevant, but state something else.

You post my intention is only to know the different ways that could be adopted in testing a the reed switch and as a result of your leading us astray Kai posted I would have posted something about statistics, error propagation, chisquare distribution, automatic testing, etc would that not have been a lot more valuable than all the useless information you got so far.

For your sake I hope you have not pi.... Kai off to the extent he will not help you with "statistics, error propagation, chisquare distribution, automatic testing", but if he will not I fully understand.
