Abstract
The utility model discloses a process signal check meter. The check meter comprises a housing, a touch screen, a USB-SD card interface, a computer, a measure circuit, an output circuit, a single-chip microcomputer, and an ARM controller. The touch screen is disposed outside the housing. The measure circuit and the output circuit are connected to the single-chip microcomputer. The single-chip microcomputer is connected to the ARM controller through a circuit. The ARM controller separately connected to the touch screen, the computer and the USB-SD card interface. The check meter utilizes good man-machine interaction interface and supports Chinese and English interfaces with simple operation. A measuring signal is completely separated from an output signal. The check meter achieves functions of automatically detecting a temperature switch, a temperature transmitter and a simulation transmitter. Thus, operation efficiency is greatly improved.
