Calibration

Notice: The CW250 scale is calibrated by the factory prior to shipment.

Calibration Enable Jumper

To access the calibration mode the shorting strap labeled "RUN/CAL", located on the
right-middle of the circuit board (Intercomp, A/D 20 BIT rev E), it must be moved from
shorting pins 2 and 3(RUN); to shorting pins 1 and 2(CAL). To access the shorting
strap, remove the 10 screws on the outside edges of the display assembly. Carefully lift
the display assembly up and place the assembly, display side down, on top of the
weighing platform.
Following calibration, replace the strap to shorting pins 2 and 3 (RUN); replace the
assembly and reattach the assembly with the screws. This will ensure that the
calibration information of the scale is protected from being changed.
Note: Care must be taken to ensure the wire harness is seated properly to
prevent it from being pinched between the display assembly and the scale
casing.
