Further, described low-voltage circuit Multifunctional electric pen, a shell surface for described display screen side be provided with turn over button and under turn over button, the side of a shell is provided with store button.
Further, described low-voltage circuit Multifunctional electric pen, described solar panel is crystal silicon cell plate, and described accumulator is lithium polymer battery, and the voltage of accumulator is 5V.
Further, described low-voltage circuit Multifunctional electric pen, the bottom of described box body is provided with detachable bottom, and the side of bottom is by hinge on box body, and the opposite side of bottom is connected with box body by buckle.
Further, described low-voltage circuit Multifunctional electric pen, the side of described shell is provided with USB interface.
The beneficial effects of the utility model are in that:
1, voltage detecting circuit and potential storage circuit are set in single-chip microcomputer, the storage of the data after voltage measurement can be carried out, shell upper surface arrange turn over and under turn over button, record data can be checked at any time, solve the problem that master worker scene notes record measurement data wastes time and energy.Shell-side face arranges USB interface, can be derived by the voltage data of storage and carry out live data analysis.
2, arranging solar panel and accumulator inside electroprobe, single-chip microcomputer is provided with solar control circuit, controls the charged state of accumulator.Accumulator is powered to electroprobe internal circuit simultaneously, solves electroprobe battery electric quantity loss big, need to often change the problem that battery is wasted time and energy.
