Design and Practice of Power Consumption Management for ZH2518 Portable Pressure Calibrator

Design scheme and engineering practice project of power consumption were proposed for ZH2518 portable pressure calibrator, based on its actual operation. The minimum power consumption management was discussed from the device and system in operation scope, firstly. Second, The above management was investigated from the following three aspects: intrinsically, operating and powering lower consumption. The theoretical design and testing research were carried out from the master computer and pressure measuring modules, respectively. Finally, the testing results show that the design scheme is reasonable and the actual operation effect of the power management system is obvious.
