In addition, the time/date of each data record is recorded.
There are more measurement types than the default set of 52. The maximum, minimum, and average
of total true power, of total VA power, and of total true power factor are not defaults, but the averages
are derived by PSM from the individual phases when the log is displayed. The seven THD
measurements (three voltage phases plus three current phases plus neutral current) are also not
defaults. To change the selected variables from the default, the Data Setup feature of PSM must be
used
(see “
). The log setup does not change when the unit is turned off.
The default setup can be recovered at any time (refer to the
Custom Consumption Data Logging
chapter).
With the default setup the log will contain 4540 records. Coupled with the default 3 minute log interval,
the default data log will hold summary data for the last 9.5 days of energy consumption (3 minutes x
4540). If 15 minute log intervals are used, the data log will hold the summary data for the last 47.3
days of logging. If logging continues long enough to fill the data log, the default is for each new record
to be written over the oldest record of the log. In this way, you could leave a unit logging unattended for
months and always have the most recent data available for analysis. To have logging stop when the
log is full or to set a programmed start or stop time, refer to the
Custom Consumption Data Logging
chapter.
Receiving Consumption Data Log from ATPOL II
To receive a consumption data log from ATPOL II, the ATPOL II unit
must be connected to a computer running PSM. At the main menu
of PSM, the green “Unit Connected” Status box must be displayed.
At the Main Menu, you can either click on the “Receive Data” button
or on the “Data” dropdown button and then “Receive Data”. In either
case, the Receive Data menu will open and all the different types of
data files in the connected ATPOL II will be displayed.
In the Data Types to Receive section, make sure that there is a
check in the box before the line “Consumption Data”. Next, look in
the tabular section for
the line with the “Log” data type entry.
Consumption logs have a To File name ending wi
th “.log”. Make
sure that the box at the start of the line is checked and then click on
“Receive and View” to transfer the data log to your computer. The
name of the file is based on the entry in the File Name box. For
instance if “psm” is entered in the File Name box, the consumption
log will be called psm.log. If you want a different root name, change
it before receiving the file.
