THE QNA-412 ANALYZER BATTERY.
The equipment has a battery for keeping the analyzer working and able to
properly record in the event of any incident occurring. The battery allows the
equipment to continue operating for 2-4 hours without mains supply. The time during
which the analyzer is to continue recording in the absence of mains supply is
programmable. In this way the QNA-412's battery can be saved and can detect
intermittent interruptions regardless of the time it takes to recharge.
The fact that the battery ensures 4 hours of operation is extremely important
because the equipment can continue recording and operating correctly in the event
of multiple and lengthy interruptions.
The battery always recharges when the analyzer
is connected to the system.
The QNA-412 Analyzer has an intelligent energy charge system This means that
the equipment is continuously monitoring the battery levels and if the charge level is
on maximum, it stops charging. This way the battery life is extended.
