| Abstract: | Combining the newly developed Virtual Instruments technology,this paper presents the design method of PTCR integrative parameter testing machine from both the hardware and software,simulating coding by computer,using the mode of 1-wire,controlling the instrument through parallel port of PC.Adopting VISUAL C 6.0 as the software develop language,it can be used to test I-T,V-I and aging characteristic of PTC and the testing results were stored,calculated,displayed and printed by software.It was proved that this system has been greatly improved than relative traditional separate instruments.The testing efficiency is been improved significantly. |
