The interval setting is the number of samplings. Since the F370's
sampling speed is 2000 times/sec., one sampling is 0.5msec.
Therefore, setting of the interval at 100 means setting of 50msec.

If the detection interval A and B are set
too short, fine load changes may be
detected as shown in the illustration on
the left-hand side, so that a correct value
cannot be held.
In this case, set the detection interval B
large enough to bring it as close to the
load change time as possible, and also
set the inflection point judgment value
large according to the amount of change
at that time, so that the inflection point
is held at a correct position.
