how to make arduino take readings from Multimeter Uni-T 61

Projects General Guidance
1

Simply I have 2 multimeters Uni-T with 2 Rs 232 shields need for my project and I cant get The Arduino to

take readings from Multimeter If any1 can tell me how to take readings from multimeter to Arduino so that

I can display them on the Screen. This will be great nd Thanks in advance.

I have 2 multimeters Uni-T

Don't know what that is, do you have a link to one or better still to the data sheet or even programming manual?

That is where you should start looking.

this is a link descriping it.

also im not a professional at using arduino but I learnt many things as I need it in my project.

thanks for the reply :slight_smile:

Google "Multimeter UNI-T UT 61B arduino" for information.

I did but nothing useful :frowning:

Is there any more information in the user manual?

I'd recommend trying to get it to work with a computer before attempting connection/communication with the Arduino.

If you have nothing to start with, try a terminal program (Windows comes with HyperTerminal).

With RS-232 you need to know the baud rate, number of stop bits, number of data bits, parity, and the handshaking configuration. (I assume handshaking isn't used with USB-serial but I don't know). If you can get readings into HyperTerminal you've guessed the right settings.

It came with software, right? Are there any clues with the software?

I found an [u]online review[/u] that conflicts with the "RS-232" claim:

and I might use it for that when I get a working RS232 to USB adapter. I do not like the UNI-T USB adapter, because it does not make a virtual COM port, i.e. it can only be used with the UNI-T software.

I don't know how to configure or program a USB shield for something like this so I can't help with that, but if you can get the computer terminal working you'll know "where you need to go".

If you buy something more-professional and more-expensive you should get detailed specs, there would be software available (for a regular computer) and you could get technical support.

...I've got a cheap digital caliper with a serial connection but there is no documentation so I can't use it (and I didn't buy it with the intention of using the serial port).
