Rotation Stops
■ About Hold ON/OFF
(1) Difference by ON and OFF of hold in stopping condition.
For Frequency and RPM measurement, results are displayed after one
confirmation cycle.
When measuring phenomena such as stopping of a rotating body, if Hold is
ON, stopping cannot be detected because there is no confirmation cycle.
When Hold is OFF, half of the previous measurement value is displayed if the
confirmation cycle does not occur within the specified time (10 ms or 1 s).
Therefore, a condition such as stopping can be estimated by gradually
approaching zero.
