| Abstract: | Digital meter of series KEITHLEY 2700 is a high-precision one with the accuracy of 6.5 bits. It can be widely used in engineering to make the measurement of various signals such as AC/DC voltage, AC/DC current,resistance, frequency, etc. On the basis of analyzing the data communication protocol for industrial 20-channel real-time measurement with the meter of KEITHLEY 2700, a real-time data acquisition program for multi-channel industrial meter is developed by using VB 6.0 on the basis of serial communication, so that the computer control of the meter and the automatization of measurement are realized. The measurement results can be recorded in access data base automatically, so that the computer management of measurement results is realized, also. Its application in engineering shows that the result is good. |
