When using the vi: "FLUKE 884X Series Read Single Measurement.vi" with a FLUKE 8846A it is reading an "overload" error message

Question

The vi: "FLUKE 884X Series Read Single Measurement.vi" can be downloaded from "http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=9431"
I want to use this driver to read out a 4-wire resistance which in deed is a PT100 resistor to measure the temperature.
When i click on the "run continuously" - button on the LabVIEW Front Panel, the program reads out the current resistance.
However after each readout there comes the "overload" - error message on the display of the 8846a multimeter.
Sometimes there can be also seen a small "error" - sign on the display and sometimes the 8846a beeps.
I already deactivated the "ID-Query" in the "Initialize.vi"
What can i do to prevent these error-messages ?

No no no. The "run continuously"  button is for debugging only and should not be used to run the program at all. If you are polling your instrument to often it will be confused. Check your timing. I think your program poll your instrument at "full speed", perhaps it works because you open and close GPIB driver on every iteration, giving some delay between each readout.    
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)
