Error -200077 occurred at DAQ Assistant

[Andy_L]

Hi,

i`m using the SCXI-1327 to aquire the Voltage of 2 signals (using Channel 5 and 6)

Unfortunately i can only record data in the range from -0.5 to 0,5 V

When i try to increase the range on MAX or DAQ Assistant i get the error below:

---------------------------------------------

Error -200077 occurred at DAQ Assistant



Possible Reason(s):

Measurements: Requested value is not a supported value for this property.

Property: AI.Max
You Have Requested: 1.000000
Valid Values Begin with: -500.0e-3
Valid Values End with: 500.0e-3

Channel Name: Voltage

-----------------------------------------------------

I remember that i`ve got Channel 5 working in a bigger range, but i dont know what i`ve done therefor

and now i must have something done to undo this

Does anybody know what to do?

Hi Andy,

this error could have several reasons.

1st:

take a look at you scaling.

Are you using a custom scaling?

If you are using a custom scaling you have to adjust the AI.Max and AI.Min level of your input !!!

2nd - you can take a look at this:

3rd at this: (nearly the same than you can see in 1st)

Hope this helps

Hi Deppi,

thank you for your response.

Today I tried what you have suggested but without succes.

I'm not using a custom scale, i tried it once but i couldn't see how this could increase my input range.

I tried to set the jumpers to "DA" so that the gain would be 1.

I thought with no gain i should get the maximum available input range?

I used a test signal from -10 to 10V on channel 1 / 4 / 5 and 6.

Now here comes something strange:

Channel 6 worked up to 10 V ( i can not tell if it would work in a higher range ) but the other channel only worked up to 5 V , though they all have the same jumper settings for the gain.

I'm not sure how the attenuation is set on the hardware, because i don't know where to set it, but also without an attenuation it should work in a higher range then +/-5V, right?

Best regards

Hi Andy,

sorry for the delay - I was on vaction for a few weeks.

That sound all really strange.

Do you still have this problem?

Is it possible to send me an MAX Export (Measurement & Automation Explorer -> file -> export...) ?

I could try to import your settings and see, if there is something strange / wrong.

Best regards

Hi Dippi,

meanwhile i was able to solve the problem.

I reconfigured the gain and attenuation settings on the hardware and in MAX and now it works as expected.

Thank you again for your effort

Best regards

Andy
