USER'S MANUAL. PROMAX-10
3 INSTALLATION
3.1
Power supply
The PROMAX-10 is a portable instrument powered by a built-in 7.2 V NiMh
rechargable battery. Before taking any measurement, the user should make sure that
the battery is fully charged (use the mains adapter supplied with the instrument).
3.1.1 Battery charge
The instrument has a 230 V / 50-60 Hz, mains adapter, for use in EUROPE and
other countries, to power or to charge the instrument. (See accessories to request other
types of adapters).
There are two different situations on battery charge:
1)
With the instrument stopped, on having connected the external power adapter,
begins a cycle of fast load which duration will depend on the battery state. For an
empty battery this time will be of 1.5 h. approximately. The charge indicator of
frontal panel will remain illuminated during this period.
On having finished the battery charge the indicator will be illuminated blinking to
indicate that a maintenance charge takes place.
2)
With the instrument working, when connecting the power adapter, this one feeds
the instrument and provides a maintenance charge, remaining illuminated the
charge indicator. The MER / BER measurements produce a light discharge of the
battery in spite of the external power adapter being connected.
ATTENTION
When stopping the instrument is reinitiated a charge
process.
It is for that reason recommendable to discharge the
battery using instrument without external power adapter
to make complete the charge / discharge process.
ATTENTION
The charge system of PROMAX-10 incorporates a
security system that does not allow the process charge
from certain temperature limit, begining the maintenance
charge instead.
CAUTION
Before using the power adapter, make sure that the
adapter is suitable for the mains voltage.
