LB 124 Scint 2. System Description
13
2.4.2 Rechargeable Batteries and Power Supply Unit
When an accumulator is used for the power supply, the option
Accu on the menu Parameter/Power Supply has to be se-
lected. With this option, the Charge Function is activated
when the charging mode is set to ON. Do not enable the charg-
ing function if batteries are in the device.
If the LB 124 Scint is connected to power or placed into the
charging station, the device is turned on automatically. The
charging process is started new depending on the settings
for cell type, charge mode and charge time. The charging
process takes place only when the device is turned on.
An activated System Timeout is not taken into account while
the charging function is active.
2.4.3 Power Supply of the Photomultiplier (PM)
Batteries and rechargeable batteries do not only supply the ba-
sic device with power. Using a fixed control voltage between 0.5
and 1.3 Volt, the high voltage of the photomultiplier is con-
trolled.
2.4.4 Power Supply and Program Memory
1. The software program, the calibration factors as well as all
fixed settings are stored in the FLASH and are independent
of the power supply.
2. The calibration factors, threshold settings, dates, measured
values, etc. defined by the user are stored in the RAM (lith-
ium battery-buffered). By means of the reset function (the
factory settings can be found under parameters/factory set-
tings), these values can be deleted; in this case, the factory-
set default values will be loaded. This function is only acces-
sible if the respective authorization to access has been as-
signed.
