How to communicate with Fluke 434 power quality analyzer via labview.

[guqunlin]

I buy a Fluke 434(power quality analyzer meter),it can communicated with windows hypterminal but can't receive anything,therefore it can't receive anything by labview also .I don't know if I must got the instrument's serial port protocol or command sheet.
Thanks for your answer.

You should certainly get the programming manual so you understand all of the commands and syntax. However, if you send a command in Hyperterminal and get a response but it doesn't work in LabVIEW, then my guess is that you're not sending a termination character. You, as the programmer, have to do that in LabVIEW. The programmer of Hyperterminal did that by sending a CR/LF when you press the enter key. Try sending both or either. If you have the manual, it should say.

Where I can get the programming manual? I don't know which command should send in the windows hyperterminal and can get the data from the serial port?

[Dennis_Knutson]

Get it from Fluke.

Sorry, i can't found any programing command in the service manual and user manual.it says very simply about serial port .

[Dennis_Knutson]

I can't find any mention of any remote control commands in the manual either. The only thing I see is the ability to dump a screen to a printer or the serial port with the provided software. Are you sure that the instrument supports anything else?

I found some dll file in the Flukeview (the Fluke company provided software),can i call the dll by Labview ?

See Chapter 2 of the Using External Code in LabVIEW manual. This will detail the steps that you need to take to use the dll for this instrument or any dll for that matter in LabVIEW. Good luck!

Hi, have you found how to communicate with power analyzer? I have the same problem.... have you found dll libraries?

thanks
