DAQmx - error 50202

When configuring an AIVoltage on a PXIe-6358 using a polynomial scale of order 3, I get the following error:

Error #-200537 Property Node DAQmx Channel (arg 1) in AIGroup.lvclass:SetBuffer.vi:7370001->AIGroup.lvclass:SetPropperties.vi:1130001-

scale = 0.522355377797965 + 10.0774426677173 * x - 0.0370658257511309 * x^2 - 0.00756509423297235 * x^3

elec range = -10 to 10

output range = -96.3835596415157 to 90.0151052468855

when using an output range = -96.2935596415157 to 89.9251052468855 it works

Please can someone explain what is the rule? or how can I bypass that issue?

Looks like you have a floating point rounding issue.  Where are you coming up with the range you are putting into the DAQmx Create Virtual Channel?  Supplying some code would help the debugging process.

Hi,

The rounding issue is not on my side, because the error message says: -96.383560 is not in the range -96.393560 to  90.025105, that is wrong.

An extract of the code is not possible because it's part of a very large S/W, and it would take a lot of time to build an usable and representative test program.

The solution we certainly will use is to leave the AI.Min and AI.Max properties unset.To be checked ASAP.
