Abstract

A transistor measuring device is an instrument that identifies polarity of each pin of transistor and various parameters. It is composed of a carry computer, a control unit, a measure interface circuit and a direct current power supply with adjustable press. computer and control unit communication interfaces are linked together; One of control unit exportation interfaces is linked with power supply control interface; The other interface of control unit is linked with inputend of interface circuit input; control unit exportation interface is linked with control unit input interface, and power supply output interface is linked with the power supply. control unit provides different voltages to the transistor pins through control unit and people can judge these pins attributes according to whether the PN stanza can transmit electric current. power supply works when people are measuring parameters. computer adopts a normal personal computer and control unit chooses a low cost, small volume chip. Moreover,the situation that computer is linked with control unit through a main line of USB makes the invention more popular.

Description

Technical field:

[0001] The invention relates to an instrument for identifying the polarity of each pin of a transistor and measuring various parameters of the transistor. Background technique:

[0002] Traditional measuring instruments for various parameters of transistors are generally realized by complex hardware circuits, resulting in high price of finished products, single function, bulky volume, and limited range of use and accuracy. Although there are also intelligent transistor measuring instruments, most of these instruments use special-purpose computers as the core and are equipped with corresponding special-purpose software and hardware boards. Due to the large hardware base of this kind of scheme, they are still bulky and expensive. Invention content:

[0003] The purpose of the present invention is to provide a transistor measuring instrument to overcome the defects of complex structure, large volume and high cost of existing transistor measuring instruments. ...
