CALIBRATION INSTRUCTIONS
1. Calibrate the scale to indicator per instructions supplied with your indicator.
2. After calibration has been completed, take a known weight (ideally 25% of capacity) and check
each corner. Place weight between center of scale and each corner one at a time as shown in
Figure 2: Junction Box Connections. Use the same calibrated weight in each corner.
3. If the indicator weight reading deviates from the known weight the junction box trim pot for that
corner should be adjusted. A qualified Scale Technician should perform this procedure. Call your
GSE Distributor for service.
4. To adjust the corner weight readings, use the trim pot designated for that corner which is numbered
the same as the corner you need to adjust. Turning the pot clockwise increases the weight reading.
Refer to Figure 1: Load Cell Configuration for the correct location.
5. After each corner has been checked and calibrated, make a final check of your calibration in all
corners and center of the scale.
6. The scale is now calibrated and ready for use.
LOAD CELL REPLACEMENT
Should a load cell become damaged due to an overload condition, replacement load cells can be
ordered from GSE Scale Systems according to the part numbers?
1. Unbolt the defective load cell, and then remove leveling load foot from the load cell.
2. Disconnect load cell cable from junction box and attach a chase wire to the load cell cable.
