  • Page 6: Overview

    Overview The CW-90/CW-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”...

  • Page 7: Tare Recall

    Allows the display of the current “under tolerance” value, or allows setting the current “under tolerance” value. When the MODE parameter is set to TARGWT or TARG% (see Section on page 19), this key is used to acquire a weight value and assign it as the desired “target” value. The CW-90/CW-90X then computes the final TARGET over/under values using the target value and the over/under tolerance settings defined during the weighing operation.

    Install feet onto bottom side of the column. 5. Turn the CW-90/CW-90X upright and replace the platter on the platform. 6. Attach indicator to the column with the two knobs and nylon washers provided. Position nylon washers between indicator enclosure and column mounting holes.

  • Page 11: Leveling

    Making Power Connections The power source used for the CW-90 must be properly grounded to an acceptable earth ground. If the indicator is remotely mounted, the platform must be separately grounded from the chassis ground screw located on the bottom of the platform.

    You can use negative checkweighing if you have an item which you want to take weight away from. For example, if a product on the CW-90/90X weighs 20 pounds and you want to remove weight in 2 pound increments, with negative checkweighing enabled, the Over value could be set to -3 and the Under value could be set to -1.
