No adjustment is required to the junction box. Refer to the manual of the weighing indicator used to perform
various settings and adjustments.
7. WHEN CONNECTING MORE THAN 6 LOAD CELLS
When connecting more than six load cells, multiple junction boxes are required.
In that case, to have a termination resistance of 100
Ω
, do the following.
Leave the jumper (JP1) in the junction box installed furthermost from the weighing indicator as is and cut
the jumpers (JP1) in the other junction boxes, using nippers.
