Record _________________________________________
The choices that
are available in this panel serve to control the device‘s
recording functions. The recording function may be switched on and off
when needed (
Recording with interval ). However, if you switch
the recording off and then you switch it on again, the memory free
space may be reduced by up to 0.2 % of its total capacity. Use
Cyclic
record in the case that you require the device to continue recording
even if the measurement data memory is filled up with data. In this case
the oldest data is gradually overwritten by the newer data. If you do not
use this choice, the data recording will be stopped on reaching the full
storage capacity. Another important parameter is the
Record interval .
It can be set from 1sec/10sec/1min (according to settings in Advanced
– Other settings (Energy) - Measuring Interval) to 24 hours (See
“
Technical parameters
”
). The recording takes place every time
at integer multiples of the pre-set interval. For example, if you switch the
device on at 5:05 and the recording interval has been set to 1 hour, the
first data will be recorded at 6:00, the following data at 7:00 and so on.
The data recording can take place either incessantly, or only
in the instant when some of the measurement values gets
into an alarm condition (system alarms do not trigger the recording).
Choose
Record mode.
By default, the device records instantaneous readings at a preset
recording interval. Another option is to select the record "average,
minimum and maximum values per recording interval". Example:
the selected recording interval will be 1h, then every 1h the three
values - average, minimum, and maximum - will be stored for the past
hour. Therefore, the next three values are saved again in an hour
and will correspond to the values in the last hour interval. Attention -
these Min / Max values are only related to the selected recording
interval and are different from the global Min / Max values displayed
on the instrument's display (these are for the entire period of operation
since their last manual reset).
The record setting is completed by choosing measurement channels
that are supposed to be recorded.
CAUTION - After changing cyclic

non-cyclic recording
(in either direction) the data recorded in the device is to be
deleted! SW warns you when saving a new configuration
and gives you the option to save data.
