• Disregarding possible jitter, the duration of the effective exposure is defined by period p (set
by Timer 1).
• Jitter may shorten or extend the effective exposure, i.e.
duration of the effective exposure = (p - 15.8 µs) to (p + 15.8 µs).
• The duration of the effective exposure can only occur in multiples of 15.8 µs microseconds.

Timer 1 must be set to a minimum of 10 µs and to a maximum of 16645 µs.
With very low exposures, use flash light.
