Questions about Load Cells

questions about the specs of load cells

when it says creep .03% FS over 30 min am I right to assume for a 1kg load cell that it will creep .03% of 1KG every 30 min? or is it .03% of the load I am putting on the cell. The second seems more logical. Is there a point where the creep slows? Say a week or two?

If it says "Recommended Excitation 10v" what are the issues if I only use 3.3v?

Hysteresis I assume is the time lag between when the force is applied and the signal but is is listed as a % of FS I don't understand.

What is the difference between "Temp Effect on Zero Output" and "Temp Effect on Zero".

there also seems to be much of a temp effect than I expected. The load cell says it is temp compensated. I guess temp comp doesn't mean no temp effect.

I have a set of plots temp/time and load cell/time but I don't know how to post it here.

most of my questions I have answered but I am still interested in creep

when it says creep .03% FS over 30 min am I right to assume for a 1kg load cell that it will creep .03% of 1KG every 30 min? or is it .03% of the load I am putting on the cell. The second seems more logical. Is there a point where the creep slows? Say a week or two?

If the cell is buildt for 1kg - your reading can vary .03% of 1kg (effective +/- 0.3 grams)
..so putting 10grams on the scale at start - it can 'creep' to 9.7 / 10.3 after some time
