<p>[QUOTE=&quot;desertgem, post: 444364, member: 15199&quot;]That model has a readability of .01gram as stated by the manufacturer. The algorithm for rounding .00x will determine the centigram reading. If x =0-4, then the 2nd digit will round to the lower number&nbsp; ( i.e.&nbsp; .074 = .07 , if .076 = .08g ) unless the platform is covered, air flow can cause a flicker between 2 numbers on the last digit. Because a carat is only .20g and a .98 carat diamond sells for much less than a 1.01ct diamond&nbsp; ( over 1 carat don&#039;t you know ~advertising) most jewelers have a scale that is .001g or .0001g readability. </p><p><br /></p><p>By the way, be careful with the pan of the scale. lifting it instead of the scale can really mess up the strain gauge sensor which does the measuring, as can putting much heavier weights than the maximum. </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
