Rif.: NI 9237 maximum voltage range accuracy

[fabio.intel]

Hello,

I'd like to know how to read the datasheet of the NI 9237 for the accuracy. If I read the web page I can read 0.038mV/V but if I read the datasheet It is more difficult.

I'm working with the load cell MT 1241 (OIML R60 C3) with rated capacity of 150Kg. When I use an external excitation (10V) I'm not abble to have a fixed value. I have 0.000xxxy V where x is fixed and y no.

Hi Fabio,

you could try to calculate the correct maximum voltage range accuracy through this document (see attachment).

Hello

           iam using Ni9237 card and iam using an 100kg load cell My objective is to measure a weight btw 0 - 50 kg.i excitation voltage is 5 v. Sensitivity of the load cell is 2mv/v. reading i get for 0 kg is 0.000646431** v/v  and for 50 kg is 0.00116299** v/v . will i be able measure a weight in grams (or atleast 10 grams ) .

** Places of digit i have mentioned in bold are fluctuating  .
