Abstract. During development and research conducted at our Institute we have repeatedly encountered the issues related to the examination of the properties of the power source for engineer equipment. These studies are often lengthy and require constant monitoring of electrical parameters of the tested object. These conditions have led to a measurement system based on measurement and programming technologies of National Instruments Company. The system is complete, but because of the great flexibility of the technology used it is not a closed system and the possibility of its expansion is virtually limitless.The article includes the description of:— programming functions;— selected ways to tailor the measured quantities to the measurement ran...
