INA214-Q1: INA214's gain error when Vsense is over 5mv

Part Number: INA214-Q1

Hi expert,

I wonder how to get gain error data over the test condition of datasheet shown below for INA214:

I searched through the datasheet and didn't get much that helps. For example, how do I know the Gain error when Vsense is from -20mV to 20mV?

Thanks

Sheldon
