3.7.4 Log Period Records
Each record has entries that contain the following information:
— Average SP (Static Pressure)
— Average DP (Differential pressure)
— Average FT (Flow Temperature)
— Calculated Volume
3.7.4.1 Log Period Data Entries
Log period data entries are made every 60 minutes, by default. The period may be changed to one of six other choices
(1,2,5,10,20,30,60). Choosing a log period of less than 60 minutes will result in additional records being logged. As such, this
requires more storage space to hold a full day’s data. The log period must never be less than the volume calculation period.
3.7.4.2 Volume Calculation Period Entries
Volume calculation period entries are made every 60 minutes, by default. The user may change this period to one of six other
choices (1,2,5,10,20,30,60). The volume calculation period should never be greater than the log period and should be evenly
divisible into the log period.
Volume calculations are completed following the top of the current period (i.e., top of the hour, top of the minute).
3.8 Display Function
During operation of the flow computer, the front panel LCD continuously scrolls through the operating parameters. Table 5
shows the typical displayed parameters; however, any parameter with a register address can be displayed. The duration that the
parameter is displayed can vary from 1 to 255 seconds (default is five seconds); a setting of zero (0) seconds will set any
display to off. See Program Display in Chapter 3 (and PCCU32 help files) for more details.
