13.3 Automatic device switch OFF

In menu item ´AOFF´ the device can be pro-
grammed to switch OFF automatically if no
key is touched for a certain settable number of
minutes; this will help save the batteries.
This automatic device switch OFF will not take
effect if the setting is ´- -´ or if a mains adapter
is connected.

13.4 Display illumination - automatic switch OFF

A characteristic of all illuminated displays is
that the illumination consumes a lot of power.
To prolong the device's operating time it is ad-
visable therefore to switch off the illumination
either permanently or so long as the device is
not being used. The display on this device is a
static transflective color segment display; even
without illumination it can be clearly read but
the characters are only black. This operating mode is likewise selected when
the data logger is in sleep mode ´SLPd´. In normal operating mode, in menu
item ´dOFF´, the user can program the number of minutes of inactivity after
which display illumination is switched OFF automatically.
device switch OFF will not take effect if the setting is ´- -´ or if a mains adapter
is connected.
