  • Page 8: Overview

    CW-90/90X Checkweigher Overview The CW-90/90X is a high-speed digital weight indicator and scale base programmed to compare weight readings with predetermined tolerance limits defining an ACCEPT band. If the current weight reading is within the acceptable range, the green ACCEPT LED is illuminated. If the current weight reading is less than the acceptable range, one or more of the red UNDER segments is illuminated.
