CHAPTER 6: SOFTWARE POWER ANALYSIS
PQM POWER QUALITY METER – INSTRUCTION MANUAL 6–23
.
The state of each data logger and percent filled is shown. Use the
START and
STOP buttons to start and stop the logs.
In the
CONFIGURATION settings, the Log Mode is set as follows:
•
Run to Fill: when the data logger is full (100%) it will stop logging
•
Circulate: when the data logger is full, it will start from the beginning and
overwrite the previous data (under development).
The
Log 1/2 Interval value determines how frequently the PQM logs each piece
of data.
The total log size is approximately 64KB. The allotment of this memory can be
varied between the two logs to maximize the overall log time. Set the preference in
Size Determination to let the PQM automatically optimize the memory. If
desired, the optimization can also be performed manually by the user.
In the
PARAMETER ASSIGNMENTS settings, the Log 1/2 Fill Time values
represent the amount of time the data logger takes to fill to 100%. This time is
dependent on the logging interval and the number of parameters being logged.
Set the parameters to be logged by Log 1 and Log 2 by highlighting the selection in
the
Assigned Parameters menu and checking the check box to assign it to the
desired log.
