If zero (0%) is entered, the terminal will NOT make any fall correction. Even if they can be totalized,
the cycles interrupted with "stop" are NEVER subjected to any fall correction.
Fall correction example.
Requested quantity = 23.5kg Fall = 3.5kg fall correction % = 10% Final quantity extracted = 26.7kg
Difference between extracted and requested quantities = Error = 26.7 - 23.5 = 3.2kg
Correction value = Error * correction % / 100 = 3.2*10/100 = +0.32kg
New Fall value = old fall value + (correction value) = 3.5 + (+0.32) = 3.82kg

Minus tolerance . This is the weight that is subtracted from the "requested" quantity to establish
the lower limit of the extraction tolerance range. The data item is only significant if the "off range"
output has been enabled.
Plus tolerance . This is the weight that is added to the "requested" quantity to establish the upper limit
of the extraction tolerance range. The data item is only significant if the "off range" output has been
enabled.
Example of how "off range" is handled.
Requested quantity = 23.5 kg Minus tolerance = 0.5 kg Plus tolerance =0.7kg
The extracted amount is off range if it is less than the value (requested quantity - minus tol.) or more
than the value (requested qu plus tol.), or if it is not within the 23 kg to 24.2 kg range.

Zero scale tolerance . This is the weight within which the scale can consider itself to be unloaded.
The data item is checked at the end of each cycle so as to deactivate the "End Extraction" and
"Off Range" outputs or not.

Initial range . This is a weight range within which the "Minimum initial weight" lower limit and the
"Maximum initial weight" upper limit can be selected. It only allows cycle start operations to be
carried out when the gross weight on the scale at the time start is requested is within the range
defined. The data item is checked upon each cycle start request and can prevent the actual
extraction cycle from starting. It could be used for determining an acceptable "empty container
weight" range. In this case, start would only be accepted if an empty container was already on
the scale.
