offset problem : DAQmxPerformBridgeOffsetNullingCalEx

[Laurent_]

Hello All,

I have an problem of OFFSET .

I explain:

I use 2 NI cDAQ-9178

Test 1:

A module 9213 is plugged on 1 NI cDAQ-9178

A module 9237 is plugged on 1 NI cDAQ-9178

If I call the function : DAQmxPerformBridgeOffsetNullingCalEx  for the module 9237, there is no problem this function returns 0.

Test 2:

The two modules 9213 and 9237 are plugged on the same NI cDAQ-9178.

If I call the function : DAQmxPerformBridgeOffsetNullingCalEx  for the module 9237, the function returns -200478

Why........

I dont understand why I get this error.

Thanks for your responses.

Hi Laurent,

Which DAQmx driver version are you using?

It seems that the behavior you have was an unexpected one:

Error -200478 occurs when using DAQmx Perform Bridge Offset Nulling Calibration with AI.Temp.TC and ...

Neverthless, it was corrected in DAQmx 9.6 (see CAR 345144):

DAQmx 9.6 Readme
