TATIC REFERENCE recorded during the teach sequence It therefore is a measure of the total process drift since the last teach sequence By setting the DRIFT LIMIT BLO x D Factor we control the maximum allowable process drift The RUO and RSO are the results of evaluating the force profile with the DRIFTABLE REFERENCE After the last teach cycle the DRIFTABLE REFERENCE is formed by copying the STATIC REFERENCE which is a weighted average of all the terminals in the teach sequence and thus at this point in time the DRIFTABLE REFERENCE is the same as the STATIC REFERENCE DRIFT COMPENSATION allows the DRIFTABLE REFERENCE to follow the process and operates as follows f a zone evaluation result is found to be less than the ZONE BAD LIMIT BLx the DRIFTABLE REFERENCE is allowed to creep by one step closer to the force curve at each point within the zone Ifthe zone result is greater than the ZONE BAD LIMIT BLx the DRIFTABLE REFERENCE is held fixed e Since the force profile is compared also to the STATIC REFERENCE the ZONE DRIFT LIMIT acts as a total process drift limit 32 DRIFT COMPENSATION therefore allows the analyser to follow slow changing variations due to common causes yet still maintain sensitivity to detect process special causes 4 5 1 Controlling Drift Compensation To turn on off DRIFT COMPENSATION From the MAIN menu select SETUP and press ENTER Select ANALYSIS and press ENTER Select DRIFT COMP
