6 Battery operation and power saving mode
PLICSMOBILE • Mobile network unit PLICSMOBILE T81
55234-EN-191217
Note:
Due to the nature of the system, each battery and accumulator has a
self-discharge which can vary considerably dependent on the type.
This is very important for the calculation of the required capacitance.
In the listed examples, this self-discharge is not taken into accunt. The
available capacitance depends also considerably from the tempera-
ture. The specifications refer to a temperature of 20 °C (68 °F).

6.5 Power options
In the DTM of PLICSMOBILE T81 (see chapter "
Parameter adjust-
ment with PACTware"
) you can select under the menu item "
Energy
options
" between the modes "
Continuous operation
" and "
Power
saving mode
".
In continuous (non-stop) operation PLICSMOBILE T81 and the sen-
sors always remain switched on. Only in this mode can the instrument
be used for level monitoring and send an e-mail when a certain level
is reached or when an error occurs (measured value/status-controlled
transmission). In continuous operation PLICSMOBILE T81 allows
remote parameter adjustment via the service department. Configura-
