Load Cell Junction Box GM-JX-M
GM-JX-M is a four-wire load cell junction box. In addition to regulating the wiring function, it can compensate for and correct the scale's four-angle deviation by adjusting the resistance value of the precision potentiometer. On some special weighing occasions, when the angle deviation is too large to affect the measurement results, this junction box can effectively solve the problem.
Four-wire Connection Method
Internal wire terminals are identified as:
"+E"-- EXCITATION +
"-E" -- EXCITATION -
"+S"-- SIGNAL +
"-S"-- SIGNAL -
"GND"-- SHIELD
Adjustment Method
Precision potentiometer W1~W4 can fine-tune the output signal of each load cell, which is used to adjust the four-angle deviation of the system.
Four-Angle Deviation Adjustment Method
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.
