Suresh said:
Then could you tell me how the average of succeding readings would be taken? Quite simple! Use the results of a series of togglings. Each high and low toggling gives you a Ucont,ss and Usig,ss reading. The next high and low toggling again gives you a Ucont,ss and Usig,ss reading. And so on. Now take the average of these readings.

If what i have stated could be a complete definition (of VCR and DCR), then i would like to know whether it could be calculated using our circuit or not? Don't make the second step before the first! First you must have a methode which reliably measures the contact resistance. Then you can think about how long you measure or how often. Kai |
