INSTALLATION
3.1 Power supply
The PROLITE-20/21 is a portable instrument powered by a 7.2 V, 950 mA/h, NiCd,
rechargeable battery. The device is accompanied by an external DC adapter which
enables the
PROLITE-20/21 to be connected to the mains for operation and battery
charging.
3.1.1 Operation using the external DC adapter
The instrument comes with a 230 V / 50-60 Hz mains adapter, for EUROPE and other
countries, for powering the
PROLITE-20/21
. (See accessories for ordering other types of
adapters.)
Once the battery is installed in the instrument, connect the external DC adapter to the
PROLITE-20/21 using the external power connector [8] located on the left side. Connect
the DC adapter to the mains, thereby starting the battery charging process. Next, press
the start/stop button [4] on the
PROLITE-20/21
. Under these conditions, the instrument
starts to function. Battery-charging time increases if the instrument is used during the
process.
WARNING
Before connecting the mains adapter, make sure that it is the appropriate one for
your mains system.
The mains adapter is designed for indoor use.
Never start the instrument with the external adapter connected if the battery is not
in place.
3.1.2 Operation using the battery
For the instrument to work using the battery, you need only press the start/stop button
[4]. With the battery fully charged and the display not illuminated, the PROLITE-20/21
has an approximate autonomy of 30 hours uninterrupted operation.
When the battery is flat, you will see the low battery indicator on the screen and,
afterwards, the instrument will automatically switch off.
