One multiturn potentiometer per load cell that shunts the output and two series output isolation resistors that limit zero interaction. Screw terminals simplify wire connection. Accepts wire size 26 to 14 AWG. Five nylon strain reliefs are included for load cells & instrument cables. Both boxes are NEMA 4X and gasketed for corrosion resistance. The GS-JB-4-SS is made of stainless steel and the GS-JB-4-FRP is made of fiberglass reinforced plastic. The small size of these boxes make them a good replacement for low profile warehouse scales. In many cases the box will fit under the platform. 7" x 4.625" x 1.75"h.
