Database Management-Retention Periods
Retention periods are selected as either days or weeks. Valid entries for the period are positive numbers from
1-99. Vertex M will not recalculate the values when the unit is changed. For example, if the purge period is 14
days and you change "days" to "weeks", Vertex M will set the period to 14 weeks. Vertex M performs the record
purge as the data acquisition computer clock passes midnight.
