General instrument functions A:5
Leonova is powered by a rechargeable lithium-ion
battery pack which is easily replaceable during meas-
urement work. A warning for low battery comes up
before the instrument turns off. No data is lost, all data
is stored in the flash memory. Leonova has a built-in
backup battery that lasts >15 years.
The battery pack in a new instrument has to be charged
before use. To release the battery pack, lift and turn
the locking screw (A), then pull out the battery pack
from the instrument.
NOTE: It is recommended to charge the battery pack at
least once a month. The reason for this is that the cells
can not withstand being fully discharged completely.
