Operating Requirements The following is a list of operating requirements necessary to operate the RoughDeck FXB flexure base scale. Electrical Grounding For systems where the scale is connected to a 120 VAC circuit, the instrument must be directly connected to an earth ground with a ground cable that has no more than three ohm resistance throughout its length and connections.
How Flexure Levers Work In the RoughDeck FXB, flexure levers replace pivots and bearings for the fulcrum and load and power points on the lever. The multiple of the lever for a flexure is calculated in the same manner as a pivot and bearing lever system.
Unpacking and Inspecting The following sections explain how to properly unpack and inspect the RoughDeck FXB for any damage. Unpacking the FXB Use the following steps to unpack the FXB. 1. Remove the banding straps. Do not remove the scale from the packing skid by placing forks from a lift truck under the base assembly unless the scale is equipped with optional fork lift skids.

Calibration and Adjustments The following sections describe how to calibrate the RoughDeck FXB. Calibration Use the following steps to calibrate the RoughDeck FXB. 1. Zero balance the digital weight indicator. Refer to your manufacture’s operating manual for instructions. 2. Place test weights equal to 70 - 80% of the scale’s capacity on the weigh platform and adjust the weight indicator span for the correct reading.

Shims are available in .010" and .030" thickness. Weight readings change in a linear way proportional to shim thickness. For example, if adding a .010" shim increases weight reading 2 lbs on that corner, a .030" shim will increase it 6 lbs. 7.
Optional Equipment The following options are available for the RoughDeck FXB flexure base scale. Option Description Fork Lift Skids Two 8" channels mounted on customer-specified centers. Fork Lift Skids w/ Weight Two 8" channels mounted on customer-specified centers with one channel extended 12"...
