Abstract
The invention relates to a universal meter capable of measuring the temperature. The universal meter comprises a universal meter body, a red meter pen, a black meter pen and wires. The universal meter body is provided with a display screen and an electrical dial plate. The red meter pen and the black meter pen are connected into the universal meter body through the wires. A temperature dial plate is arranged on the left side of the electrical dial plate. The temperature dial plate is provided with an air temperature gear and a liquid temperature gear. A single-chip microcomputer is arranged in the universal meter body. The electrical dial plate and the temperature dial plate are connected to the single-chip microcomputer through internal wires. The red meter pen and the black meter pen are each internally provided with a control valve connected to the single-chip microcomputer through an internal wire. The universal meter overcomes the defects that according to an ordinary universal meter, only the electrical engineering data can be measured, the function is single and the ordinary universal meter cannot be fully utilized, and the function of measuring the temperature is added.
Description
Technical field
The present invention relates to single-chip microcomputer product scope, particularly relate to a kind of can the multimeter of measuring tempeature.
Background technology
Multimeter is a kind of surveying instrument of widespread use, and volume is little, portable, and measuring accuracy is higher, but common multimeter can only measure electrotechnics data, and function singleness can not be made the best use of everything.
Summary of the invention
In order to solve the defect that in above-mentioned prior art, function of multimeter is single, the invention provides a kind of can the multimeter of measuring tempeature.
Technical scheme of the present invention is as follows:
A kind of can the multimeter of measuring tempeature, comprise multimeter main body, red test pencil, black meter pen and wire, described multimeter main body there are display screen and an electricity dial plate, described red test pencil and black meter pen are wired in multimeter main body, described electricity dial plate upper left side has a temperature dial plate, described temperature dial plate is free temperature degree shelves and fluid temperature shelves two gears, described multimeter body interior has a single-chip microcomputer, described electricity dial plate and temperature dial plate are connected on single-chip microcomputer by inner conductors, a by-pass valve control is respectively had in described red test pencil and black meter pen, be connected on single-chip microcomputer by inner conductors.
Described by-pass valve control can control to change red test pencil and black meter pen measures electrotechnics data, or measuring tempeature data, be measure air themperature or fluid temperature, and by-pass valve control is by Single-chip Controlling during measuring tempeature.
Described single-chip microcomputer adopts stm32 single-chip microcomputer model.
Advantage of the present invention is: compensate for common multimeter multimeter and can only measure electrotechnics data, function singleness, the defect that can not make the best use of everything, add thermometric function.
