ames are “Prog 1” through “Prog 5”. These can be renamed
and the values set using TrakPro

specific start time or date was selected using TrakPro
™ software, the
instrument will wait until the start time and then automatically begin
logging. If the start time/date is in the past, the instrument will show
the error message "Invalid start time."
