The function of the JBA, strain gauge active junction box is to enable easy adjustment of strain gauge (output) manufacturing tolerances without any channel interaction to give a summated output.
The JBA is used to sum the outputs from up to 4 strain gauges 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 strain gauges.
Gain is not interactive and offset is preset, to speed up matching of strain gauge gain.
