INPUTS FUNCTIONING
Each input can work individually in positive or negative logic. A holding time (de-bounced time) attached to all inputs can be
configured.

General functions
9.2.1
None
Inputs have no effect.
9.2.2
Tare
One or the other or both inputs can be assigned to the tare function. The tare acquisition is conditioned by a stability
criterion that can be changed or inhibited.
Depending on the chosen logic (positive or negative), the tare is triggered by a rising or a falling edge.
9.2.3
Cancel tare
Depending on the chosen logic (positive or negative), the current stored tare value is erased by a rising or a falling edge.
9.2.4
Zero
One or the other or both inputs can be assigned to the zero function.
A new volatile zero value is acquired only if its value is within ±10% range of the specified capacity for a usage out of legal for
trade and ±2% for legal for trade application. The zero acquisition is conditioned by a stability criterion that can be changed
or inhibited.
Depending on the chosen logic (positive or negative), the zero is triggered by a rising or a falling edge.
9.2.5
Transmit measurement
This is only possible using standard or fast SCMBus format or CANopen® protocols.
The request can apply to:
gross measurement.
