4-3-2. Load Cell Installation
1) You can connect Max. 8pcs of same capacity Load cells at once. (350Ω)
2) You have to make horizontal balance on the ground.
3) If you install more than 2pcs of Load cells, use Summing box and adjust output signal difference
as minimum. It can make wrong weighing process caused by each load cell’s variation.
4) If there is some temperature difference around Load cell, it can cause wrong weight measurement.
5) Don’t do Welding job or Arc discharge around installation place. But, there is no choice,
please disconnect power cable and Load cell cable.
6) If you measure static electricity material, please make earth between down part and up part
of Load cell.
