13.7 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.
