25<p>Gets the strength of zero-point drift correction.</p><p><B>Note:</B> The stronger the effects of correction, the closer the return value is to <CODE>1.0</CODE>; but do not mistake this value for an indication that correction has completed. There are situations where a value close to <CODE>1.0</CODE> is returned even though correction is insufficient, and other cases where correction is complete even though the return value is close to <CODE>0</CODE>.</p><!-- write here --></div>
