Resistance on the input terminals can be measured with three methods, two, three or four wire connection. In all cases U-I method is used for .measuring Enforced current causes a voltage drop on measured RTD sensor which is supplied to the programmable amplifier B. After A/D conversion the .signal is computed in microprocessor The measured value determined by the microprocessor is assigned to the programmable analogue output .Communication D enables programming of the measuring transducer and monitoring of the measuring resistance on the input terminal DOWNLOAD FILE
