2.6. Battery charge
This equipment has an internal battery charger with a smart,
microprocessor-controlled circuit which adjusts the battery charge to the
optimized parameters to ensure the maximum service life. It is supplied by
an external source for 220-240 V∼ (supplied with the equipment) or by a
12 V car battery.
In order to recharge the battery, connect the equipment to the mains supply
or to the external battery. After a few seconds, the BATTERY CHARGER
STATUS LED" will flash during one second in green and red alternately.
During this period, the charger checks the battery initial status, selecting in
this way the charge optimized parameters. After this, the BATTERY
CHARGER STATUS LED" will remain lit in red until the charge is
complete, then the led will turn into green and will remain this way until the
equipment is disconnected from supply.
If, during the battery charge with 12 V car battery, the equipment is used to
perform measurements, the charge will be momentarily interrupted,
returning to the charge process once measurements are finished. In the
following table we summarised the meaning of the luminous indications of
the LED"
Alternate green and red lights
Evaluation of the battery initial status when the
source is connected, during one second.
Steady red light Battery under charge.
Flashing red light The battery was not successfully charged. It de
some trouble in the battery charging process.
Steady green light The charge has successfully finished. The battery is
OK.
Note: Under storage, the battery loses part of its charge. Thus, before using the
equipment for the first time, or after some time of being out of use, the battery must
be recharged. As the kind of rechargeable battery that this equipment uses does not
show the “memory effect” and due to the charger intelligent characteristics, there are
no restrictions to start charging it as many times as is needed. As soon as the
charger detects that the battery is completely charged, it will automatically turn to the
Float state (Green indication), protecting it from overcharging.
