5.5.- On-board battery of the QNA-303 analyzer
The
QNA-303
analyzer is equipped with an intelligent energy charging system.
This means that the instrument continuously checks in an automatic way the status
of the battery, thus the charging process stops when the battery is at its maximum
charge level and, therefore, the life span of the battery is increased.
When the analyzer is connected to the main, the
battery is self-recharging.
The analyzer has an inner battery to assure the power supply of the analyzer
when any event occurs. This battery permits to keep the analyzer continuously
energized during 4 hours in case of lack of voltage supply from the main. This period
of time of operation after a voltage supply loss is user-programmable in order to
economize the battery charge and to assure the detection of possible intermittent
voltage interruptions.
The warranty of a 4-hour operation period is essential to assure the proper
detection and recording of multiple and long-term voltage interruptions.
6.- SETTING THE QNA-303 UP
The
QNA-303
analyzer performance will depend on the user-configuration of the
instrument. To accomplish this configuration, two different setup sections can be
distinguished:
•
Operation Setup: To define the
QNA-303
analyzer operation mode.
•
File Setup: To define the data collection procedure of the
QNA-303
into the
internal memory. (In this model, all parameters are fixed and cannot be user-
changed).
