ANJ-200 intelligent pulling force instrument was designed for measuring pulling force of tractor. Through employing modern elements and advanced software technology, the product has realized automatic correcting of error of zero point and digital filtering, and a high accuracy is obtained. Less power is needed and little temperature effect happens due to the wide use of CMOS IC. Because the circuit applied common voltage, it has eliminated the error resulting from the increasing and decreasing of the voltage. The diverse indicators of ANJ-200 intelligent pulling force instrument have passed the test and its parameters achieved or exceeded the standard of the same trade. Consumers′ application in one year has shown its good performance. The quality of product had passed the appraisal from Anhui Science and Technology Committee.
