The function of the JBA active load cell junction box is to enable easy adjustment of load cell (output) manufacturing tolerances without any channel interaction, to give a summated output.
The JBA Junction Box is used to sum the outputs from up to four load cells to allow them to be connected to the LCA15/ADW15 Strain Gauge Indicator/Controller.
The individual channel gains can be set up via DIL switches and preset potentiometers to allow for 2, 3, or 4 load cells.
Gain is not interactive and offset is preset, to speed up matching of the load cell gain.
