Statistical Computation(TLOG)
You can configure up to three timers for statistical computation.
The TLOG timer (1 to 3) is assigned to each statistical computing channel.
Each TLOG timer has configured parameters as follows.
Mode
: Absolute or Relative
Absolute
Interval
: Select from 1,2,3,4,5,6,10,12,15,20,30min,
1,2,3,4,6,8,12,24hour
Reference time
: Input 00:00 to 23:00
Relative
Time
: Input 00:01 to 24:00
Reset
: You can select whether to reset the results of statistical calculations upon time-up of each
interval, or to retain the results and continue the calculations.
ON
; Result of computation is reset
OFF ; Without resetting data
Action
: Define behavior on timeup
OFF
; Without appending the data in file on timeup
Data save
; Data is saved in internal memory at timeup.
In Auto save mode, data is saved in external media automatically.
Intervals of Statistic calculations
The intervals of statistical calculations (TLOG) can be specified and set as starting from either:
A specified time
or
The time when mathematical calculation (MATH) starts
(1) Specified Intervals from Specified Time (example)
(Setting)
Mode
: Absolute
Interval
: 2h
Reference time
: 00:00
*After mathematical calculation (MATH) starts, the first interval of the statistical calculations
(TLOG) ends when the nearest interval time, which is determined by the
Reference time
and
Interval
setting, is reached.
(2) Specified Intervals from When Mathematical calculation (MATH) Starts (example)
(Setting)
Mode
: Relative
