Waɗannan lanƙwasan suna da mahimmanci don cikakken ƙirar kewaye da fahimtar halayen na'urar a ƙarƙashin yanayi daban-daban. Yayin da ba a bayyana takamaiman zane-zane a cikin rubutun da aka bayar ba, yawanci sun haɗa da:

• Dangantakar Ƙarfin Haske da Ƙarfin Gaba:Yana nuna yadda fitar da haske ke ƙaruwa tare da ƙarfin tuƙi.
• Ƙarfin Wutar Lantarki na Gaba da ƙarfin Gaba:Yana kwatanta halayen IV na diode.
• Dangantakar Ƙarfin Haske da Zafin Muhalli:Yana nuna raguwar zafi na fitar da haske.
• Tsarin Kusurwar Dubawa:Zanen iyakacin duniya wanda ke nuna rarraba haske na sararin samaniya.

Sashen jagoran mai amfani yana haɗa bayanai masu amfani don aiwatar da LED, gami da shimfidar gado na PCB da aka ba da shawarar (don ingantaccen samuwar haɗin solder da zubar da zafi), girma na tef, da ƙayyadaddun reel, yana tabbatar da dacewa da kayan aikin masana'antu.
