Assembly

Unpacking

Carefully remove the bench scale from its box, ensure that it is not damaged, and that all the parts are included. This scale has been factory calibrated and only needs minor assembly.

• T104P Indicator with Check Weigh and Counting
• Bench scale with load cell and spider assembly.
• Column and hardware kit, “wrench included”.
• Platter

Installing the Column

• Assemble the bench scale and the column by inserting bolts into the threaded holes as shown in the image below. Put washers on the bolts then using the supplied wrench tighten the bolts until all bolts are tight.
• After fastening the column to the base install all the bench scale and column leveling feet as shown in the image below.
• Place the bench scale on an environmentally sound level surface and adjust the feet on the bench base only. (Do not adjust the column feet at this point) until the bullseye level shows that it is level as shown in the image below. Once the scale is positioned and level adjust the column feet until they sit firm to the surface (It is important to make sure that the column feet are taking the pressure off the column only). Finally, tighten all lock nuts.

Overload Stop

The overload stop is a set crew placed on the underside of the base and is designed so that the load cell bottoms out when more weight is applied than the scale’s capacity. To adjust this screw simply apply the weight that matches the capacity of the scale plus 5% and adjust the screw in until it hits the cell. The overload stop is now set to stop at anything over 105% of the scale’s capacity. Use blue Loctite when setting the screw.

Indicator Installation

• Mount the indicator on the column mounting bracket. Tighten the wing nuts to secure the indicator to the column.
• Plug the load cell cable connector into the back side of the indicator load cell connector.
• The load cell connector and load cell cable have been factory terminated. The diagrams below show the termination points for reference.

NOTE: Your scale has been factory calibrated, however, the scale should be tested to confirm its accuracy after shipment.

• After calibrating the scale, test it at the low end, middle and high end to ensure it is working properly. Once the scale is confirmed working, the scale is now ready for use.

Positive Check

• Positive check is used to determine when the material added to the scale is within the target weight range. In this case, the under and over-values must be positive values. (The overvalue must be greater than the undervalue.)
• To start, add material to the scale pan until the display turns green.

Negative Check

• Negative check is used to determine when the material removed from the scale is within the target weight range. In this case, the under and over values are both negative values. The undervalue must be greater than the overvalue. (For example, the undervalue is -10; the overvalue is -15).
• To start, place a package or bin of material on the scale and press the Tare button. Remove a portion of the package or material until the display turns green.
• To continue weighing multiple portions off the scale’s pan, tare the scale between each portion.

Zero Check

• Zero check is used when comparing subsequent samples to an initial reference sample. In this case, the undervalue must be zero or a negative value and the overvalue must be zero or a positive one.
• Place the reference sample on the scale and press the Tare button. Remove the material from the scale pan until the display turns green.

Load Cell Replacement

• Install the load cell using supplied B-TEK ASP-1 load cell and shims. Torque the B-TEK ASP-1 load cells to 76 in. lbs.
