Temperature effect on span of load cell usually quoted as a percentage of full scale this is the change in output at full load due to temperature changes. e.g. 0.01%/10°C means a change of up to 0.01% of full load output per temperature change of 10 degrees C. 

This function is very important for the load cell application in different temperature. without temperature compensation, the accuracy will be very bad, and the load cell reading will be too much different than actual weight.
