7.7.3 Storage of logged values
Logged values are saved with time stamps and flags that indicate events that have occurred during the logging
interval.
• The time stamp indicates the end-time. If the logging interval is configured to one hour, a value with the
time stamp 15:00 refers to the period 14:00 to 15:00.
• To indicate events or states during an interval, a logged value can be stored with one or more flags.
Event or state
Name of flag
Explanation
Time adjusted
T
During the past interval, the meter clock has been adjusted either instantaneous
or a sliding adjustment is in progress.
Time Disturbed D
The past interval is incomplete. For example, an interval shortened by the meter
being without auxiliary power or if the logging memory has been reset. The first
value after the logging memory having been configured will thus always be
indicated with "Faulty value” (the logging memory is reset in conjunction with
reconfiguration).
Alarm
A
In conjunction with user-defined alarms being configured, it may be specified that
an alarm will also be indicated with logged values. When a user-defined alarm has
triggered during the past interval, this is indicated with the flag “Alarm”.
Parameter
changed
P
The Prometer 100’s configuration, calibration or initiation has changed. Which of
these three the flag refers to can be seen in the event log.
