Weighing module is a measurement module with high accuracy, which can be used for low level signal down to 1.5μV reliably. To acquire operation with no fault, it's essential to assemble and wire cable correctly.
Following these rules to wire the weighing sensor:
Voltage measurement wire SIG+/SIG-
Power voltage wire EXC+/EXC-.
4.The shield must be connected to the shielded joint clamp.
4-wire connection for the weighing sensor
When connecting 4-wire sensor, you must terminal the EXC+ with SENS+, EXC- with SENS-, or else the module cannot work normally.
6-wire connection for the weighing sensor
