SEMI-AUTOMATIC TARE (NET/GROSS)
THE SEMI-AUTOMATIC TARE OPERATION IS LOST UPON INSTRUMENT
POWER-OFF.
To perform a net operation (SEMI-AUTOMATIC TARE), close the NET/GROSS input or activate the
function through the communication interface. The instrument displays the net weight (just set to
zero) and the NET LED lights up. To display the gross weight again, keep the NET/GROSS input
closed or deactivate the function through the communication interface. This operation can be
repeated many times by the operator to allow the loading of several products.
Example: put the container on the scale, the display shows the container weight; close the
NET/GROSS input, the display shows the net weight to zero; introduce the product in the container,
the display shows the product weight. This operation can be repeated several times.
The semi-automatic tare operation is not allowed if the gross weight is zero.
COMMUNICATION INTERFACE
To activate the semi-automatic tare, send command 7 to CMDR; the value in NW is updated.
To deactivate the semi-automatic tare, send command 9 to CMDR.
