and ground the shield wire.
Next, remove connector J1 from the single-channel A/D card. The connector plugs into a header on the A/D card.

cards, remove jumpers JP3 and JP4 for connections to J2.
When connections are complete, reinstall load cell connector on the A/D card and use two cable ties to secure the
load cell cable to the inside of the enclosure.
