Internal balance

My question is aboutthe internal balance of the TGA Netzsche 449 F3 Jupiter.

When Ipress "weigh"to tare the balance and then weigh out my sample to analyse, a message appears:

"Cannot weigh using internal balance. Instrument is off"

Please cananyone tell me how toswitch on the instrument (I presume it is the internal balance, not the TGA). Thank you in advance.

    Netzsch - TG 449 F3 Jupiter®
    DESCRIPTION
    The thermobalance for every application - robust and upgradeable

    The TG 449 F3 Jupiter® is the workhorse for thermogravimetric analyses of a moderate to high sample weights from -150°C into the high temperature range of 2000°C. The vertical design with top-loaded samples ensures total protection of the balance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top, with optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet. The TG sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample. The high capacity of the balance along with constant resolution over the entire weighing range provide the best conditions for using the wide variety of ceramic or metallic sample crucibles and pans in different shapes and sizes. Of course, vacuum-tight construction providing for pure atmospheres goes without saying. The TG 449 F3 Jupiter® is designed for upgrading to simultaneous TG-DSC or simultaneous TGA-DTA. The TGA sample carriers can be exchanged with TGA-DSC or TGA-DTA sample carriers in a matter of seconds so that a very cost-effective upgrade can be made at any time into a full-fledged, universal STA. The TG 449 F3 Jupiter® is one of the versatile TGA systems for routine use in material research and development as well as in quality assurance – primarily in the area of inorganics.
