Showing weird symbols and letter instead of my datas

[Ben_Manthey]

Is this really the place for grammar lessons?

Back to your actual question....

Minipa has a nice website and they have a Model ET-2801 which if I were a betting man I'd say was the updated version of the ET-2800. Does it look similar to you? Also, I'd bet that the commands and  data format are identical. My Portuguese doesn't extend to finding their programming manual. Perhaps you can find it.

Well... yes, actually.  Kind of.  Part of becoming a successful engineer is to know stuff like that.  It increases your engineering cred.  You don't really want to be talking about "datas" in front of your peers.  But point taken.  I steered the ship off course.

Thanks.

I saw this model yesterday and it has some diferences and similarities'but the manual say nothing about programation 😞

I'm gonna send later some screenshoots on VISA panel test, I don't know if it will help

I think  that I found the solution, but I need you help cause I don't know how I do that.

I send a e-mail to the manufacter and today they send me the protcol to this multimeter.

I don't know hot to configure to send that data and how to decod on LabView.

(this protocol is used on another software, only for win 95/98)

According to the documentation, the communication is an exchange between the PC and the DMM where the PC sends a five-byte command (0x55 0x55 0x00 0x00 0xAA), and the DMM sends back a 59-byte response. Most of what you'll be sending and receiving is not text, so you'll want to disable the Termination Character option on the VISA Configure Serial Port. First you'll do a VISA Write with that five-byte command, followed by a VISA Read for exactly 59 bytes. After the successful read, you'll need to break apart the received string into all the different fields described in the manual: first the four byte prefix 0x55 0x55 0x00 0x36, then the 8-byte Model Name, then 8-byte Series Number, 7-byte S/W Version, 1-byte Switch Code, etc. Once that's broken into individual fields, you can decode those fields using all of the lookup tables in the rest of the manual. I'd try to start by getting the VISA Write and Read working first. If you run into questions with that, just ask.

it might work like this (saved for labview 2013)

the acquisition part. not the parsing part

[arteitle]

That should work, but it's a lot more complex than it needs to be; almost everything inside the While loop could be replaced by just the VISA Read with a timeout of 450 ms and a byte count of 59. And there's no need for all of those nested Case structures, just wire the error out of each block to the error in of the next one, they'll know what to do if there's an error.

jupp .. but i like my personal space for error handling 😉

But hope for no one will inherit your LV code. Otherwise those persons will not say nice things about you, when they need to refactor/clean up your code 😄
