Hi all,

 

I have a  fluke 8846 multimeter that im using to measure temperature , i need to log the data with labview , for this i donwloaded the ni drivers for  my fluke 8846 , but whe i run the examples , more especifically the  Fluke 884X Series Read Temperature Measurement.vi  , the multimeter  makes a couple of beeps , a click sound and the lcd  refreshes , the vi stops with only one measure recorded (the last one before the blinks), i want to log the temperature in the vi as it chnages in the multimeter, i dont know what could be the problem.

 

I cheked the config  on the multimeter , ports on the pc and in max , im using a serial to usb cable.

 

whe i check with the visa test panel  , this si what i get

There is not a status byte on a serial port.

Try \r as the terminator. You may be able to change this from the instrument front panel. I don't know what the driver is set to buy you can quickly check that by looking at the block diagram. And please provide the errors that you get with the driver.
