11.4 Evaluation Unit LB 442
After power on, the instrument identification must appear on the
display and with <more> you go on to the operating parameters
of the various menu structures. If no entry is made, the program
automatically switches from the current menu to the display mode
after a few minutes.
The evaluation unit includes an error monitoring device which also
covers the detector functions and displays error codes indicating
instrument faults. For information on the error and the potential
cause see the Error Code Listing. If a hardware error occurs, the
evaluation unit has to be replaced.
If no error code is displayed, this means that the electronics is
working correctly and all measured values and parameters are
within the normal range. Possible function problems must then
have another cause. Please refer to the 11.2 Trouble Shooting.
A total reset should be performed only in exceptional cases and af-
ter consultation with Berthold Technologies
A total reset is performed by pressing the Clear key – while the in-
strument is turned off – and turning the instrument on at the same
time.
11.4.1 Battery
If the computer is without power supply (power down or separated
from mains), the clock is supplied with power by a battery. No de-
cay compensation is performed during this time. This will be done
as soon as the evaluation unit is connected to mains. Decay com-
pensation is performed when the date changes.
The service life of the battery, even in case of continuous stress,
i.e. when the evaluation unit is not connected to mains, is 7 years.
