Startup & the Setup Wizard The Setup Wizard This screen defines the standardization condition, the standardization time and the level of the material in the pipe at standardization. 3-16 LevelPRO User Manual Standardization On – The two options for the standardization condition are Empty or Not Empty. STD Sample Time (sec) – The standardization sample time is the amount of time, in seconds, that the detector will average the incoming signal. Choosing an appropriate value for this parameter will depend on your process conditions. In situations where the process level is quite steady,and stable the vessel should not have any significant swings in the percentage, and, therefore, the detector count should be stable. Under these conditions, a relatively short standardization time, in the order of 60 to 300 seconds may be appropriate. When standardizing on a changing level, . In these conditions it is desirable to use a much longer sampling time, more in the order of 600 to 900 seconds.
