General sensor resistance signal simulation circuit of examining test table of four motormeter in state

The utility model discloses a general sensor resistance signal simulation circuit of examining test table of four motormeter in state, the analog circuit who includes and treat the oil mass resistance signal that instrumentation is connected, the analog circuit of oil mass resistance signal includes the resistance network who comprises adjustable resistance more than three or three and switch, resistance network one end ground connection, instrumentation is treated in other end connection. During the use, it is small, with low costs through the resistance of adjusting adjustable resistance, the resistance that can adjust whole resistance network, still including the analog circuit who treats the temperature resistance signal that instrumentation connects, the analog circuit of oil pressure resistance signal. Oil mass resistance signal can not only be simulated to sensor resistance signal simulation circuit, but also can simulate temperature resistance signal, oil pressure resistance signal. 本实用新型公开了国四汽车仪表通用检测
