3. Analyzer Battery Pack The analyzer has its own Li Ion battery pack which is automatically charged when power is applied from the NMT System If the power goes out in the NMT System the analyzer will keep running for up to an additional 8 hours In this case data will be stored in the analyzer but depending on the communication protocol and equipment used data may or may not be able to be sent to the central management system e LAN via ADSL for example Data can be sent to the Server e GPRS The GPRS router is powered via the NMT unit s power supply mains or QB 0065 thus if power goes out in the NMT then the router cannot transmit data NOTE When powered from the analyzer battery pack only Alarm Reports Weather Reports and GPS Reports cannot be made CHAPTER 6 Power Start up and Calibration 39 6 2 Start up When ready the analyzer will start up and after a short time the NMT monitoring template will start running From a cold start it may take up to two minutes Fig 6 2 Start up display on the analyzer Hand held Analyzer Type 2250 Briel amp Kj r Subsequent start ups depend on the state the instrument was in when last switched off If the analyzer was in Standby mode it will only take about 10 seconds to start up If the analyzer does not start automatically when power is applied press the power button Q on the instrument 6 2 1 Setup the Memory Device Data are streamed from the NMT to th
