6.- THE QNA-P/PV ANALYZER’S INTERNAL BATTERY
The analyzer has an internal battery to ensure power supply to the analyzer when
any event occurs. This battery keeps the analyzer continuously powered for 2-4
hours in the event of the mains power supply being cut. This operating period after
voltage supply loss is user-programmable in order to save the battery and to ensure
that any possible intermittent voltage interruptions are detected.
The guarantee of a 9999 second operating period is essential to ensure the
proper detection and recording of multiple and long-term voltage interruptions.
The battery is charging when the analyzer is
connected to the mains.
The QNA-P/PV analyzer is equipped with an intelligent energy charging
system . This means that the instrument continuously and automatically checks the
status of the battery. This means that the charging process stops when the battery is
on maximum charge level and, therefore, the life of the battery is increased.
