in place for a four-wire load cell. Locate the ferrite core kit and follow the included "load
cell cable grounding and ferrite assembly" instruction sheet.

Multiple Load Cell Connections

The maximum number of load cells that can be connected to terminal block TB1
depends on the total resistance of the load cells connected in parallel. This total must lie
within the load resistance limits specified in the table below.

The remote switch and serial communications terminal is found on the top of the main
board next to the transformer. Remove the rear cover to access these connections.
Connections are made by inserting each lead of the optional cable into the P2 terminal
