Instrumentation system and error

  1. Apr 11, 2005 #1

    i have a question about instrumentation system and error.

    An amplifier in an instrumentation system exhibits a zero drift of 1/2 percent of full scale per hour. Determine the error if the measurement of Q0 is taken six hours after the initial zero was established and if the amplifier is operated at one half of full scale.

    I am using the book called Instrumentation for Engineering Measurements by James Dally. The thing about this book is that it doesnt give any examples on how to solve the problems. I keep looking for an equation, but i cant find any. If anyone could point me to the write direction, or some hints, that would be supper dupper!

    thanks a million.
