measurement and automation

[jdsnyder]

I am just getting started using The Measurement and Automation Explorer.   Half an hour ago, I performed a temperature calibration to familiarize myself with the process.  It appeared to work.

I tried to calibrate a second time.  It says my present calibration is 12/31/1903 - Question 1) why is this?

I pressed the <calibrate> button, then entered my calibrator's name, then

I left the calibration characteristics as it was one the screen: 1000 samples at a rate of 1000 hz, then I pressed <next>

I received the following message:

Error 50103 at the DAQ assistant.  - Question 2)  What is this error code for

Question 3) where can I find a list of error code numbers and their meanings? 

Thanks,

First off error code 50103 states that the specified resource is reserved -- Basically saying that some other process on your machine is already using that particular daq device.  The easiest way to know more about error codes you can check in at www.ni.com --> and search the error code number. Searching for this error code I found the following KnowledgeBase Article: http://digital.ni.com/public.nsf/allkb/485201B647950BF886257537006CEB89?OpenDocument This exxplains all of the possible reason for why you could be getting this error. 

Secondly if you are in LabVIEW you can use:  Help>>Explain Error and this will give you all of the information you need regarding this error code. 

 Usually that date (12/31/190) is set as the calibration date when the device being used or being calibrated is a simulated device.  What is the color of the icon next to the device in MAX?  If it is yellow you are using a simulated device.  If it is green then it means you have good hardware and it is being recognized properly by MAX.  If that is the case I don't really know why you would get that particular calibration date.

Also, What kind of device are you using? is it an NI Device?  If it is NOT an NI device it is possible that it is not designed to work in MAX and therefore could be the reason for the wierd calibration date.  Also what is this calibrator you speak of how and where are you specifying 1000 samples @ 1000hz.  Let us know!

Thanks,

I had two problems - one two devices were assigned the same channel.

   But, that did not clear the error.

Then, I  noticed the samples  to read was  set at  100,  but  the  calibration  was  set for 1000 samples.

When I changed the  samples to read to 1000, the error cleared.

By the way, I am using an NI  CB37F-LP

I spoke too soon.  I ran the start of the calibration one time to check for error messages, when I didn't get the error message, I sent you the response.

Then, I re-ran the calibration to actually perform a calibration, I got the error message again.

OK, now the problem is finally solved!  I re-set the device.

It worked the first time, but then had to be re-set. 

Thank you,
