У меня есть регистратор picolog 1012, на который я должен взять большой объем данных. Программное обеспечение по умолчанию действительно неприятно для использования, и PicoTech предоставляет несколько простых example script, позволяющих записывать данные в excel. К сожалению, он регистрирует только данные из двух каналов, а у меня девять.Журналирование picologger для excel с использованием vba
Мне удалось отрегулировать интервал и время регистрации, но я не могу правильно настроить количество каналов.

Может ли кто-нибудь пролить свет?
Это что-то, что любой, кто ничего знает о VBA, может решить, или вам нужно знать пиколог? Очевидно, что если ничего другого, то нужно проверить пиколог, чтобы проверить код правильно.
