VIII. SET THE SAMPLING TIME FOR DATA LOGGING
Press the SETUP button several times until SEC is displayed in reverse video.
Press the
▲
or
▼
buttons to increment or decrement the value (users can set up
the sampling time from 2 sec. to 3000 sec., step by 2, e.g. 2 sec., 4 sec., 6
sec., … ). Holding the
▲
or
▼
buttons will speed up the process of
incrementing or decrementing.
To exit, press the EXIT button.
The example about how to decide the sampling time for data logging:
If users want to log data for
3 weeks
and the power system is
3P4W
, first clear the
memory of the analyzer, then set up the sampling time as 104 sec. or more. See
the calculation on below:
3 (weeks) x 7 (days) x 24 (hours) x 60 (min.) x 60 (sec.) = 1,814,400 (sec.)
1,814,400 (sec.) / 17,474 (the max. file capacity of 3P4W) = 103.83 (sec.)
