
Switch the display off manually or program it to automatically shut off by itself (see §4.3.4);

Disable the fast acquisition mode of the measures which was possibly enabled while the
instrument was switched on (see §5.2.5).

Cancel not-used actuation logics (see §5.5);

Manage modem switch on through actuator 7 (programmed with timed logic), or
programming GPRS communication through modem activation (see §3.1.1);

In case of sensors or telephone modems fed continuously, don’t use instrument’s batteries,
but use other ones (if possible). In this way the instrument can operate even if modem and/or
sensors aren’t fed, and so they aren’t operating;

Disable communication protocol on serial port 2, in case it isn’t used or in case it
corresponds to following types: TTY, Modbus, Gill anemometer.
ATTENTION : Default configuration programmed on instrument is not the one of lowest energetic
consumption.
In case of Slave devices:

The Slave devices must have a channel to measure battery (level battery or voltage) that
bypasses the internal acquisition mode, normally set at one minute. The low energetic
consumption is achieved by programming the measure with a higher acquisition rate (5
minutes or more recommended).

It’s important don’t turn off (accidentally or otherwise programmed) the device “parent” of
the Slave because before the next attempt to send data, the Slave should enter into a search
mode (which still has a limitated duration) that consumes a lot of energy.
