GMA-JB4-Ex is an intrinsic safety explosion-proof junction box that supports connections for 4 analog or digital load cells in 4-wire. By adjusting the resistance value of the potentiometer, it compensates for angle deviations, effectively resolving inaccurate weight results caused by angle differences in weighing applications. Stainless steel housing with 5 explosion-proof cable glands (BDM-II G1/2)(Ex Marking: Ex db llC Gb, IP Rating: IP66), applicable cable outer diameter: φ5-12mm, delivers enhanced protection and superior anti-interference performance. Certified for intrinsic safety explosion-proof standards, it is ideal for deployment in hazardous environments.

Before adjustment, the four-channel potentiometer is gently rotated to the middle position;
Fine-tune the channel with a large deviation to the average value (close the other three channels when observing one channel);
Repeat step 2 until the millivolt signals of the four-channel are similar.
