General - Advanced - LCD Display ___________________
These settings are used for optimizing the backlight of the display in
relation to your application. As a default, the Multilogger is set in a way
that the backlight (
LCD backlight activity ) is activated only for several
seconds upon the last key pressing. If, however, you need to ensure a
good visibility of the display in the mains powered fixed installation, turn
on the backlight activity only when the external power supply is on and
choose a suitable intensity (
LCD backlight intensity ). If the backlight is
permanently turned on while Multilogger is powered from the batteries,
they discharge relatively fast, therefore do not use this setting. Turn
the backlight off for applications, for which is required the longest
battery life.
Record _________________________________________
This options are used for controlling the record functions of the
Multilogger. Recording can be turned on and off as needed (
Recording
On/Off ). However, if the record is turned off and then you turn it on
again, this takes up 0.1% of the free memory capacity. Use the Cyclic
record if you require the device to continue the recording even when
the data memory is completely full. In this case, the oldest data are
replaced by new ones. If you do not use this option, the recording will
stop once the memory is full. Another important parameter is the
Recording interval . It can be set from 1 second to 24 hours (see the
Technical Information ). The recording is performed in integral multiples
of a set interval. For example, if you turn the device on at 5:05 a.m. and
if you have set the logging interval at 1 hour, the first data will be
recorded at 6:00 a.m., next ones at 7:00 a.m., etc.
Recording can be continuous or, alternatively, records can be taken
only if any measured quantity is in the alarm state (the system alarms
does not trigger recording). Moreover, Multilogger with binary input No.
3 also offer the option to control the recording by the status of this
binary input. These settings can be performed in the section
Recording
mode .
By default, the device records the actual values at the time of the
recording interval. However, if continuous recording is on (see above),
you can select recording of average, minimal and maximal values
during recording interval. These settings can be performed in the
section
Recorded values.
