USER'S MANUAL. PROLINK-4
3 INSTALATION
3.1
Power Supply
The PROLINK-4 is a portable instrument powered by one 7.2 V - 11 Ah Li-Ion
battery. There is also an external DC charger provided for mains connection and battery
charging.
3.1.1 Operation using the External DC Charger
Connect the external DC charger to EXT. SUPPLY [38] on the PROLINK-4 side
panel. Connect the DC charger to the mains. Then, press the PROLINK-4 on/off key
[1]. The level meter is now in operation and the battery is slowly charged. When
the instrument is connected to the mains, the CHARGER indicator [7] remains lit.
3.1.2 Operation using the Battery
For the device to operate on the battery, disconnect the power cable and press
the on/off key
[1]. The fully charged battery can power the equipment for more
than 2 hour non-stop.
If battery is very weak, the battery cut-off circuit will prevent the device from
functioning at the same time the beeper will be heard. In such a situation battery must
be recharged immediately.
Before taking any measurements, you have to check the charge state of the
battery by checking the battery charge level indicator BATTERY [8] on the front panel,
or Battery & Lnb function on the TV mode functions menu (see section '4.9.4.3
Batteries and External Units Power Supply').
The BATTERY [8] led indicates, whenever the equipment is off and connected
to the external DC charger, in a qualitative manner the battery charge condition. For
battery charge levels close to 100% it remains lit in green colour; for charge level higher
to 50% it remains amber and it appears in red to indicate the empty battery condition.
When the instrument indicates a Low Battery (led lit in red colour) the battery must be
charged immediately. When the low battery level is reached, the monitor momentarily
displays the message VERY LOW BATTERY and the beeper sounds.
