How to install a LabJack (U3)?

Hi
i looked at the U3 docs and figured that might be one way to get to be able to use over 2.4 volts
do you have any Delphi or c++ code samples for how to set the labjack into that mode?
(Maybe there is in the u3 docs (i think from memory i did see something there)

i tried setting the output voltage to drive the EI-1022 to only 2.5 instead of 5, but that meant the voltage coming back was not changing much with temperature changes

if the voltage coming back from the EI-1022 could be halved with a resistor, and then doubled again in the code, would that work?
