Abstract
In view of the defects of the existing hand-held Multimeter in measurement, such as difficult to operate and low measurement accuracy, a new type of component measurement device based on controllable distance expansion is proposed, and its detection system is designed and studied based on the device. By using LabVIEW programming software as the development environment and calling DAQ assistant function to configure the relevant voltage and current parameters, the DAQ acquisition board module integrated in the measurement device realizes the interactive communication between the data, and realizes the voltage and current acquisition of the system control. The experimental results show that the system can detect the voltage, current or resistance of components quickly, and the system has strong readability and high data precision.
