Blectrogrsph type 43-2

.Tho Electrograph type 43-l is un ecuipmant thot enables carrying out glectrogrephic photopxophs of the difforont ports or tho boiies of humon beings, aniznls, ports of plonts snd so on.

Before connecting the rpperntus olrecdy on tho high =D tension laed out e tello serving fcr carrying out the eloctronphic photos, eventuclly sone-electrcie to be usod, have to ba connectui. It is unidsiseble to let the epperotus connected whenever ths lied-out hes not been chargad by a suitable electscde.

Onee connected the cloctrode we want to use for photogruphying purposes, ve connrct the pover moin : switch locatei in the right banl upper corner of the : apporatus penel. it the geze tizo tha pilot laup mounted above the. said switch hes to linhten up. Since that moment the spperstus is completely reudy for operation end electroprsphic photoa cen be carried out.

shon wishing to expose ty one high tension dischshlo only, we hiore the butten for the "ischrrse frequenco insertad ond wo precs the pueh button mcuntcc next to tho circuit switch.

In thot coso eoch pressing or tho push button produceg o unicue discheres thot will ba used for the exposwrp parpoaas. If, however, wo wish to nrke exoeures ty dischcrgos leatins somo tine ond following gach othcr in a rspid wey, we extrect the button with tha help of which the discharga frecuency is adjusted. Thus tho generStor is got workine, ons which automotically sats working ths hich tension chjrgee, os woll es the frecuencies, which crn be rogulsted within the lizits of soue l-50 cps by the button designeted FRLEVLlCE /Frequency/.

As mcntinnad previously, if we wont to photogrcph, for inat. the fisures of a hend it is sufficient to ley tho hond in question on tho top of the sansitive meterisl, on account of tho fect, that cny men stonding on the floor is grounded-evon if such esrthins is of a small ccpacity ong, snd thus connectei with cne high tension poie. If, howover, we want to ahot somo parts of plcnts, it cocs not sufiics to lcy thom cn the photogrophic materisl. In such o case it is better to disccnnect the feed supply to the toble's electrcda snd touch with the said power supply directly the moterial we wish to shot. The high tension power mein is closed sgoinst the eorth across the proper tables copacity, the ghotogrophying being made possible this way.
