The range of the displayed values, type of input signal, scale bias, and name of the
channel are defined by the user.
6.1.3.
Recording momentary and averaged data
Values corresponding to the results of current measurement conducted for each channel
can be recorded (stored in the non-volatile memory of the unit) for further analysis. The
recording of measurement results for all channels is performed with the same frequency,
defined by the user in the range between 1 record per second to 1 record per hour
("
Rec.
period
" parameter). Recording times are synchronized with the internal real time clock.
Recording can be stopped at any moment with selected status on digital input of the unit
("
Triggering
" parameter).
In order to enable more advanced mathematical processing of recorded signals it is
possible to set the unit's options to record averaged measurement results. Setting the
recorded value type to
averaged value
(parameters "
Channel 1
"... "
Channel 8
", depending
on the number of channels in the unit) causes that instead of momentary values the unit
records in its memory values that constitute the average results of measurements conducted
during the set
recording period
. All measurements conducted by the unit shall be averaged,
irrespective of the set recording frequency.
