3.1

Power supply

The PROMAX-26 is a portable instrument powered by a built-in 12 V NiMh
rechargable battery. Before making 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 mains adapter to power or to charge the instrument.
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 3.5 h. approximately. The battery charge indicator
on the frontal panel will remain lit in amber during this period.
When the battery charging is completed, the light will change to green, indicating
that a maintenance charge is taking place.
2) If the instrument is operating and the voltage adapter is connected, this serves to
power the equipment and to provide a battery maintenance charging; in this
situation the charge indicator remains in green.
ATTENTION
Whenever the equipment is power off or
external voltage adapter is connected a battery
charging process restarts.
It is for that reason recommendable to
discharge the battery using instrument without
external power adapter to make complete the
charge / discharge process.
ATTENTION
incorporates a security system that does not
allow the process
temperature limit, begining the maintenance
charge instead with
green/amber until the temperature downs to the
required value.
CAUTION
Before using the power adapter, make sure
that the adapter is suitable for the mains
voltage.
