摘要：
The present invention provides compensation for temperature in a transducer by connecting the adjustment resistors to the transducer itself to provide a correct transducer output. A number of switches are used to couple the adjustment resistors to the transducer circuit. An individual resistor may be coupled in parallel or in series with a transducer resistance. The control input for the switches are each coupled to a separate bit output of a multiple bit memory. The memory is programmed to control the duty cycle of the switches when addressed.
