1. Choosing a place for the microscope
Before starting, choose a sufcient location for microscoping. Please take care that your
microscopestandsonanevenandsolidground.
Positionyourdevicesothatitcanbedisconnectedfromthepowersupplyatanytime.The
wallsocketshouldalwaysbelocatednearthedeviceandbeeasilyaccessible,sincetheplug
onthepowercordservesasadisconnectingdeviceforthepowersupply.
2. Illumination
WiththeAnalythSTRyouhavethreeilluminationoptions:incidentlight,transmissionlightand
both.First,connectthepowersupplytoapowersupplysocketandthenintothepowersupply
connectionofthemicroscope(14).Now,engagethemainswitch(6).
Theilluminationforincidentlightandtransmittedlightcanbeadjustedseparatelybyusingthe
twobrightnesscontrolbuttons(7and8).Afterswitchingoff,theselectedsettingisretained.
Alternatively, the Analyth STR can also be operated with batteries.To insert the batteries
(type AA), open the battery compartment (13) on the underside of the microscope.
Make sure that the polarity is correct. The microscope can also be used with the
power supply when batteries are inserted. Rechargeable batteries will not be charged.
