RoughDeck AX 2.5.1 Trimming Procedure Trimming is a process of equalizing the output from multiple individual load cells. If needed, load cell output can be individually trimmed with potentiometers. Whenever a substantial amount of trim (more than 5% of normal output), seems necessary to equalize output, check for other possible problems.
Access Ramps Access ramps for the RoughDeck AX are designed to bolt to the floor, with built-in mounting plates that attach to the scale feet. When used with access ramps, side movement of the scale is automatically eliminated, and no other mounting plates are necessary.
RoughDeck AX 3.0 Adjustments and Calibration Mechanical Adjustments To accommodate minor unevenness, scale feet can be used to adjust scale height up or down a fraction of an inch. Adjust the feet using the top access foot adjust holes until all feet are contacting the floor equally. No jam nuts are supplied for locking the feet, as there is a slight decrease in accuracy when jam nuts are tightened.
RoughDeck AX Load Cell Replacement Replacement load cells can be ordered from Rice Lake Weighing Systems. To remove a defective load cell, lift the scale with chains and proper spreader bar and remove foot. Then, remove defective load cell. Disconnect load cell cable from junction box and cut cable ties. When the cable is freed, pull cable out of the scale frame channels.
