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.
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 .
