Logging Chapter 6
Data Log Results Files
The PowerMonitor 5000 unit stores the data log in multiple comma-separated-
value (.csv) files, and selects a file duration based on the value of the
Data_Logging_Interval parameter.
In addition, the active data log file is closed and a new file is created when any of
the following events occur:
• Initial powerup of the power monitor
• Subsequent powerup, if the active data log file is older than the expected
duration
• If the Data_Logging_Interval or any other data log parameter is changed
The Data_Log_Mode parameter determines what happens when the log contains
60,000 records:
• If set to 0 = Fill and stop recording when log is full, no new data log files
are created and no more data is logged.
• If set to 1 = Overwrite when log is full starting with the earliest record, a
new file is created and data logging continues uninterrupted. This is the
default setting.
File Names
Data log file names have the following semantics:
DataLog_YYYYMMDD_hhmm_HH.csv, where:
• YYYYMMDD_hhmm - the file creation date and time
• HH - UTC hour avoids duplication during daylight-saving time transition
