If you set up the upper limit value to a value equal to or less than the lower
limit value, the limit range is not used. This operation is equivalent to
setting the limit range to OFF.
If BINs overlap, the resulting measurement is sorted into the BIN of the
smallest number (refer to
page 133). Therefore, you need to set up the limit ranges starting from the
narrowest to the widest as shown in
For the tolerance mode, the reference value is not required to be within the
limit range (between the lower limit value and upper limit value).
Gaps between the limit ranges are allowed. Therefore, you can set up the
limit ranges as shown in
