Подскажите, пожалуйста, как здесь перевести слово pitch.
Контекст: система видеоинспекции печатного полотна, описание функций и настроек системы.

Перед этим речь шла об измерении длины рапорта.

Set the range that a _pitch_ graph shall indicate (in millimeters). The _pitch_ graph indication range is expressed by the values before and after the measurement range relative to the pattern length serving as reference.

Set the number of _pitches_ required to restore the inspection after starting to take measurements.
If too short a number of _pitches_ should be set, the detection master may be obtained with the correction remaining unstable. It may sometimes lead to a wrong detection, which would cause a lot of flaws to take place.

Set whether or not to let the flaw list indicate a _pitch row_.

Заранее спасибо всем!
