Power supply

The PROMAX-25 is a portable instrument powered by a built-in 12 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 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 2.5 h. approximately. The charge indicator on the
front panel will remain lit in red during this period.
When the battery charging is completed, the light will change to green, indicating
that a maintenance charge is taking place.
2) When the charger is connected with the device on it powers the device and
supplies a maintenance charge. The charge indicator will be off.
ATTENTION
If during the charge process the equipment is power-on, this process stops and it
will be reinitiated again when the instrument is power-off.
ATTENTION
Whenever is connected the external adapter to
the equipment a charge process will be
reinitiated.
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-25 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.
