Instructions
J2362 simple resistance box adopts plastic glue sealing structure. The resistance value transformation is in the form of rotary switch, which depends on the electric drama rotating to different positions to achieve the purpose of resistance value transformation. The panel layout is shown in Figure (1), and the principle in line is shown in Figure (2). The resistance element of this instrument adopts precision resistance and highly stable precision alloy manganese copper wire 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 it is used, it is connected to the circuit through two terminals on the panel, and a resistance value of 0-9999 Ω can be obtained by adjusting the four knobs. The resistance indication is obtained by multiplying the readings of the indicator points by the times marked above and then adding them together. Generally, the value of the indicator points of the knobs is read from the high times to the low. This value is the resistance indication.
