QUADRATURE RATE
Rate and direction may also be displayed using an extended version of the counter. Using
quadrature to determine rate not only has the advantage of displaying direction but also
eliminates errors due to vibration and jitter that cause erroneous readings in standard rate
meters. The meter uses A-B to display quadrature rate. Scale 1 is used to set A to the
proper value and scale 2 is set to identical values. Rate (I1) is the difference between
Channel A and Channel B.
