Hi everyone. I have VC8145 and MASTECH MS8050 bench multimeters. I can connect these multimeters to the computer with the rs232 port. But both multimeters don't have disk. I can't download the driver to my computer. How can I get the driver or disc for these multimeters. The location is Azerbaijan. Thanks for your attention.

 

Both meters need the special option software available from the manufacturers to record and display the data on a computer. Contact them on-line.

 

If you are familiar with RS-232 interfaces, you should be able to connect to the meter, determine the baud rate, and transfer data to any program that can access the PC COM port. I would usually use MATLAB for a situation such as this one.

RS232 is a bi-directional interface. The difficult part will be figuring out what the protocol and commands are needed to send to the meter to get it to transmit any useful data.

 

The pdf explains that an adapter board is needed to convert the old RS232 0-5V to -3 to+3V
Meterman-Vc8145 is for unattended reading and logging using command line software for windows.

Another source code was developed by monitoring port while running the command line version of Meterman by Paul Daniels using C++

I do not have experience with these. There are warnings, read very carefully!, it is easy to mess up the RS232

 

It is hard to find a PC that has RS-232 COM port.
Going from 0-5V UART to USB is more typical now.

 

I can use it? PC have HDMI conn
