Minimum: For any horizontal scale setting, the minimum holdoff is 10 times that setting,
but is never less than 1 ms or longer than 5 s.
Maximum: For any horizontal scale setting, the maximum holdoff is at least 2 times the
minimum holdoff for that setting, but is never more than 10 times the minimum holdoff for
that setting.
