DAQmxGetAIChanCalCalDate gives Current Date &Time

[Chemist_and_Crystallographer]

When I try to get last calibration date of the devices, I get Current Date&Time not the calibration date& Time.

 nistatus := DAQmxCreateAIVoltageChan(tempnitaskhandle,
                                                                     @tempcreatechannellistchr,
                                                                        '',
                                                                     DAQmx_Val_InputTermCfg_Diff,
                                                                      -5,
                                                                      5,
                                                                   DAQmx_Val_VoltageUnits2_Volts,
                                                                   #0);
nistatus:=DAQmxGetAIChanCalCalDate(tempnitaskhandle,@tempcreatechannellistchr,@tempyear,@tempmonth,@tempday,@temphour,@tempminute);

Hi Omer,

I wouldn't expect any data back from the USB-6009 since it does not support self or external calibration. However, for your 6013E, I would like for you to go to Measurement and Automation Explorer and go to the calibration tab for your 6013E. See what date and time show up there. If you can get data from there, then try running the function again with just the 6013E.

Regards,
Hal L.

Hi Omer-

The DAQmxGetAIChanCalCalDate() property does not return device calibration information but rather information about when a software channel calibration was last performed via the MAX interface.  If you want to retrieve the hardware calibration date and time you should use DAQmxGetExtCalLastDateAndTime() or DAQmxGetSelfCalLastDateAndTime().

Hopefully this helps-

Thanks,

I always expext that every function works on every NI products.

Hi Omer-

Some functions are not applicable to all devices, but in this case you should be able to use the functions you need.  Is it safe to assume you are up and running with your app now?

Thanks-
