Product Description Product DescriptionTeaching resistance box for Students Teaching InstrumentProduct IntroductionJ2360 demonstration resistance box is an anatomical form of plug type resistance box, which is used to demonstrate the basic structure and principle of plug type resistance box, and can also be used as a general constant value resistance.Product Specification Product nameTeaching resistance boxAccuracy classLevel 1Adjustable range of resistance0 ~ 9999.9 Ω The minimum step value is 0.1 Ω.Operating temperature0~40oCRelative temperature25%~80%Zero resistanceR0<0.035ΩReference power50Wrated power1WmaterialplasticSize165×125×60mmInstructionsJ2361 teaching resistance box adopts bakelite sealing structure. The resistance value transformation is in the form of a rotary key switch, which is achieved by rotating the brush to different positions. The resistance element of the instrument is made of highly stable precision alloy manganese copper, which is wound on the porcelain skeleton in a non inductive manner. After strict screening, testing, aging and immersion treatment, the resistance value is stable and correct. When in use, it is connected to the circuit through two terminals on the panel, and a certain resistance value in the range of 0~9999.9 Ω can be obtained by adjusting five knobs. Generally, the value of each knob at the indicated point is read out in sequence from high multiples to low ones, and this value is the resistance indication.Detailed PhotosProduct ParametersCompany ProfileCertificationsPackaging & ShippingFAQ
