Load Cell Connection - A&D AD-4408A Instruction Manual

5.2. Load Cell Connection

Connect the load cell cable to the terminals as shown below.
Use a 6-wire shielded cable to connect a load cell, especially when the cable is long
or when summing multiple load cells, to avoid drift caused by changes in
temperature.
If the cable is short, a 4-wire shielded cable with terminals 1 and 2 (EXC+ and
SEN+) and terminals 3 and 4 (SEN- and EXC-) connected may be used, but the
error increases when summing multiple load cells and the cable is long.
