| Abstract: | The design technique of adjusting-free intelligent thermometric instrument with thermal resistance sensor is advanced. In the instrument zero and gain are dynamically calibrated with reference resistor. The zero error, gain error, zero drift and gain drift are analyzed. A dynamic calibration algorithm causes that the error and drift to be only under influence of 4 resistors. The performance of instrument designed with the technique is outstanding. The design technique has been used to design calorimeter.1fig.,4refs. |
