1 1. COMPARATORS. 2  2. 3  The general principle of comparator is to indicate the differences in size between the standard and the work being measured by means of some pointer on a scale with sufficient magnification It thus does not measure the actual dimension but indicates how much it differs from the basic dimension. Basic operation 1. 2  The comparator is first adjusted to zero on its dial with a gauge block in position 2. 3  The work piece to be checked is then placed in position 3. 4  The comparator gives the difference in dimension in relation to the gauge block.
