Load Cell Junction Box GM-JX-V

GM-JX-V is not the normal and traditional load cell junction box. In addition to regulating the wiring function, it can compensate and correct the four-angle deviation by adjusting the resistance value of the precision potentiometer. On some special weighing occasions when the angle deviation is so large to affect the measurement results, this junction box can effectively solve the user's problems.

Adjustment Method

Precision potentiometer VR1~VR4 can fine-tune the output signal of each load cell, which is used to adjust the four-angle deviation of the system.
Four-channel dip switches SW1 to SW4 are used to disconnect or connect the corresponding load cell. When it is in the OFF position, the load cell is disconnected from the system. When it is in the ON position, the load cell is connected to the system.

Four-Angle Deviation Adjustment Method

Before adjustment, the four-channel potentiometer is gently rotated to the middle position;
Observe and record the millivolt signals transmitted of each load cell separately through the dip switch (close the other three channels when observing one channel)
Fine-tune the channel with a large deviation to the average value (close the other three channels when observing one channel)
Repeat step 2 and step 3 until the millivolt signals of the four-channel are similar.
