Multifunction DAQ
PCIe 6259 aquacition speed
Hello: 
I am using LabView 8.5 with a PCIe 6259 Daq card. The card functin fine, I can read and write signal to and from it.
My problem at thai moment it is in a section of my programming. I have created a testing module in wich I have place a folder to select different information or actions.
On the front (folder 1); I have my auto test mode, second folder; I have testing perameters form a data base, third folder; I have a test result view or print, on the fourth folder I have Manual test, and the last folder have calibration requirements.
Manual testing : In this section a unit can be maually test it. The operator selects the voltage and load or no load to be use them presses the extend or retract button -- no problem it works.
Auto testing: In this mode the operator selects a unit model from the database the test perameters are download to the test module then the operator inserts the unit for testing and presses the test button. The first and second section of the module work fine when it gets to the third section it starts ok but while is running I am checking for current and keeping the load constance. I have a sub VI for the current since the current will have picks and vallys I am performing an averaging during the test. For the constance load the logic is part of the test VI.
The problem it seems to be that when running in auto test mode the current seems to be building up instead of averaging up to about 2.00 amps at the most and the load seems to shoot up to the max load then drop down by now the logic has seems the current increases higher then a fail test accurs. The manual test and auto have the same type of logic
the out the same current avareging and load control.
Any boddy have any ideas what I am or could be doing wrong.
