Local Operation
Logged data, statistics and some functions are available in these windows:
• HISTORY STATISTIC accessible by menu item MEASUREMENT / HISTORY / SHOW
• HISTORY VALUES accessible from HISTORICAL STATISTIC via Val function (F5 or 5 key)
HISTORY STATISTIC Window
Description of window items:
1
st
Line:
- window ............ name of the window: “HISTORY STATISTIC”
- quantity ............ name of the quantity for which statistic is shown. Names of all quantities:
"Active Power [W]", "Voltage [V] ", "Current [A]", "Reactive Power[VAr]",
"Apparent Power [VA]", "Phase U [°]", "Phase I [°]", "Distortion U [%]",
"Distortion I [%]", "Frequency [Hz]"
2
nd
& 3
rd
Line:
- STATE .............. state of the history functionality: “running” or “stopped”.
- MEMORY ......... used memory percentage (0 - 100 %)
- BEG .................. date and time of first logged value (= beginning of logging)
- END .................. date and time of last logged value (= end of logging)
4
th
- 6
th
Line:
- ACT[x] .............. actual (last) measured value of channel x (=1, 2 or 3)
- MIN[x] ............... minimal measured value / it’s date and time of channel x (=1, 2 or 3)
- MAX[x] ............. maximal measured value / it’s date and time of channel x (=1, 2 or 3)
7
th
Line:
- AVG[x] ............. average of all measured values of channel x (=1, 2 or 3)
- STDEV[x] ......... standard deviation of all measured values of channel x (=1, 2 or 3). Value is in
parentheses when not actual (new value was measured after last calculation of
STDEV value)
8
th
Line – keys:
- 1 or F1 .............. key for starting / stopping of logging. All measured values and statistics are
available after stopping of logging until next start or until performing reset
(which is available from MEASUREMENT / HISTORY submenu)
- 2 or F2 .............. key for (re)calculation of statistical values (minimal, maximal, average and
standard deviation values) for selected quantity. Recalculation is done
automatically if quantity is changed during stopped logging. When quantity is
changed during running logging then recalculation has to be called manually
for achieving statistical values or actual standard deviation.
- 3 or F3 .............. key for selecting quantity for which statistical values are shown. Quantity can
be changed also during running logging but recalculation has to be called when
statistical values are needed.
