3.3 Installation and start up
The
PROLITE-20/21
has been designed for use as a portable instrument. When the
battery is inserted in its housing and the instrument switched on, for a few seconds, the
display will show the name of the instrument and the software version. E.g. in the case of
the
PROLITE-21 :
Figure 3.-
A fully charged battery will power the instrument for some thirty hours if the display is
not illuminated. The battery should be recharged when the low battery indicator (LB)
appears on the display.
When installing a completely flat battery, you may find that the PROLITE-20/21 starts
up due to residual charges, however, the instrument will automatically disconnect before
the low battery indicator appears on the display.
