Blocking Function - Ahlborn ALMEMO 710 Operating Instructions Manual

13. Settings
13.6.6.2 Language
In the function ´Language´ the user can, via a selection box, choose between
German / English / French as the interface language in which the functions are
labeled in the display; (other languages are also available as options). If Ger-
man is not set as the language, outputs via the interface will appear in English.
13.6.6.3 Date and time-of-day
For the purpose of logging actual measuring durations this device incorporates
a real-time clock with date and time-of-day; this clock is very precise (2 ppm,
equivalent to maximum 0.2 s/day). It is powered by a lithium battery ensuring
that date and time-of-day are retained intact even if the battery pack is com-
pletely discharged. Date and time-of-day are always visible in the top line. Se-
lecting this field calls up a menu in which the date can be programmed in the
format d.m.y and the time-of-day in the format h:m:s.
13.6.6.4 Illumination
The display can be brightly lit but using this illumination can be very power-con-
suming. If the ambient light is sufficient ´Display brightness´ can be substan-
tially dimmed without adversely affecting legibility. This saves energy and
makes for a much longer ´Operating time´ when the device is run in battery
mode. It is also possible to program a period of time, after which, if the device
has not been used, it will automatically switch to ´Energy-saving mode´ and re-
duce its ´Display brightness´ even further. It is also possible by means of 'En-
ergy-saving mode' to disable the display completely. It will return to normal dis-
play brightness as soon as any key is pressed.

13.7 Blocking function

To protect the device against unauthorized use and generally to facilitate nor-
mal operation it is possible in the menu ´Block function´ to enable / disable ac-
cess to a particular menu or functions by simply clicking on it.
In the functions ´Configure menu block´ and ´Configure function block´ the de-
sired enable / disable setting can then be entered quickly and easily. These
settings can be activated by means of ´Activate block configuration´. The user
will now be asked to set up a password, which will have to be entered again at
the same juncture in the function ´Deactivate block configuration´ in order to
deactivate the block. So long as a block configuration is active, the yellow LED
´LOCKED´ (5) will remain lit. (see 9.4)
In the main menu by means of the function ´Select block configuration´ any of
the 5 standard block configurations ´Lock1´ through to ´Lock5´ can be called
up. When one of these is called up it can be suitably renamed in .
