Weighing With Tolerance Range - KERN FES 17K-4 Operating Instructions Manual

13 Weighing with tolerance range

Setting a tolerance range allows you to quickly check whether a weight value is
within certain limits.
You can define either a single tolerance value (either minimum value as lower limit or
maximum value as upper limit) or a tolerance range (minimum and maximum value
as lower and upper limit).
Weighing with tolerance range is available for the following applications:
Weighing, percent weighing, piece counting and coefficient multiplication.
Whether a measured weight value is within certain limits is indicated on the display in
the bottom line by a flashing message (see table below).

Weight values can be evaluated in two ways when weighing with a tolerance range:
• Evaluation of absolute values
o The evaluation is based on the permissible maximum and / or minimum
value specified.
• Evaluation with difference values
o The evaluation is based on a specified reference value and the
permissible difference values.
Example:
A sample may weigh a minimum of 900.0 g and a maximum of 1200.0 g. The table
below shows which values must be specified for the respective differentiation
methods.
